Deuteronomy — Chapter 20

Loading ESV text...

1When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them: for the LORD thy God is with thee, which brought thee up out of the land of Egypt.

2And it shall be, when ye are come nigh unto the battle, that the priest shall approach and speak unto the people,

3And shall say unto them, Hear, O Israel, ye approach this day unto battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them;

4For the LORD your God is he that goeth with you, to fight for you against your enemies, to save you.

5And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it.

6And what man is he that hath planted a vineyard, and hath not yet eaten of it? let him also go and return unto his house, lest he die in the battle, and another man eat of it.

7And what man is there that hath betrothed a wife, and hath not taken her? let him go and return unto his house, lest he die in the battle, and another man take her.

8And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and fainthearted? let him go and return unto his house, lest his brethren’s heart faint as well as his heart.

9And it shall be, when the officers have made an end of speaking unto the people, that they shall make captains of the armies to lead the people.

10When thou comest nigh unto a city to fight against it, then proclaim peace unto it.

11And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that is found therein shall be tributaries unto thee, and they shall serve thee.

12And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:

13And when the LORD thy God hath delivered it into thine hands, thou shalt smite every male thereof with the edge of the sword:

14But the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take unto thyself; and thou shalt eat the spoil of thine enemies, which the LORD thy God hath given thee.

15Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.

16But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth:

17But thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites; as the LORD thy God hath commanded thee:

18That they teach you not to do after all their abominations, which they have done unto their gods; so should ye sin against the LORD your God.

19When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by forcing an axe against them: for thou mayest eat of them, and thou shalt not cut them down (for the tree of the field is man’s life) to employ them in the siege:

20Only the trees which thou knowest that they be not trees for meat, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it be subdued.

1When thou goest forth to battle against thine enemies, and seest horses, and chariots, [and] a people more than thou, thou shalt not be afraid of them; for Jehovah thy God is with thee, who brought thee up out of the land of Egypt.

2And it shall be, when ye draw nigh unto the battle, that the priest shall approach and speak unto the people,

3and shall say unto them, Hear, O Israel, ye draw nigh this day unto battle against your enemies: let not your heart faint; fear not, nor tremble, neither be ye affrighted at them;

4for Jehovah your God is he that goeth with you, to fight for you against your enemies, to save you.

5And the officers shall speak unto the people, saying, What man is there that hath built a new house, and hath not dedicated it? let him go and return to his house, lest he die in the battle, and another man dedicate it.

6And what man is there that hath planted a vineyard, and hath not used the fruit thereof? let him go and return unto his house, lest he die in the battle, and another man use the fruit thereof.

7And what man is there that hath betrothed a wife, and hath not taken her? let him go and return unto his house, lest he die in the battle, and another man take her.

8And the officers shall speak further unto the people, and they shall say, What man is there that is fearful and faint-hearted? let him go and return unto his house, lest his brethren`s heart melt as his heart.

9And it shall be, when the officers have made an end of speaking unto the people, that they shall appoint captains of hosts at the head of the people.

10When thou drawest nigh unto a city to fight against it, then proclaim peace unto it.

11And it shall be, if it make thee answer of peace, and open unto thee, then it shall be, that all the people that are found therein shall become tributary unto thee, and shall serve thee.

12And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it:

13and when Jehovah thy God delivereth it into thy hand, thou shalt smite every male thereof with the edge of the sword:

14but the women, and the little ones, and the cattle, and all that is in the city, even all the spoil thereof, shalt thou take for a prey unto thyself; and thou shalt eat the spoil of thine enemies, which Jehovah thy God hath given thee.

15Thus shalt thou do unto all the cities which are very far off from thee, which are not of the cities of these nations.

16But of the cities of these peoples, that Jehovah thy God giveth thee for an inheritance, thou shalt save alive nothing that breatheth;

17but thou shalt utterly destroy them: the Hittite, and the Amorite, the Canaanite, and the Perizzite, the Hivite, and the Jebusite; as Jehovah thy God hath commanded thee;

18that they teach you not to do after all their abominations, which they have done unto their gods; so would ye sin against Jehovah your God.

19When thou shalt besiege a city a long time, in making war against it to take it, thou shalt not destroy the trees thereof by wielding an axe against them; for thou mayest eat of them, and thou shalt not cut them down; for is the tree of the field man, that it should be besieged of thee?

20Only the trees of which thou knowest that they are not trees for food, thou shalt destroy and cut them down; and thou shalt build bulwarks against the city that maketh war with thee, until it fall.

1When you go to war against your enemies and see chariotry and troops who outnumber you, do not be afraid of them, for the Lord your God, who brought you up out of the land of Egypt, is with you.

2As you move forward for battle, the priest will approach and say to the soldiers,

3“Listen, Israel! Today you are moving forward to do battle with your enemies. Do not be fainthearted. Do not fear and tremble or be terrified because of them,

4for the Lord your God goes with you to fight on your behalf against your enemies to give you victory.”

5Moreover, the officers are to say to the troops, “Who among you has built a new house and not dedicated it? He may go home, lest he die in battle and someone else dedicate it.

6Or who among you has planted a vineyard and not benefited from it? He may go home, lest he die in battle and someone else benefit from it.

7Or who among you has become engaged to a woman but has not married her? He may go home, lest he die in battle and someone else marry her.”

8In addition, the officers are to say to the troops, “Who among you is afraid and fainthearted? He may go home so that he will not make his fellow soldier’s heart as fearful as his own.”

9Then, when the officers have finished speaking, they must appoint unit commanders to lead the troops.

10When you approach a city to wage war against it, offer it terms of peace.

11If it accepts your terms and submits to you, all the people found in it will become your slaves.

12If it does not accept terms of peace but makes war with you, then you are to lay siege to it.

13The Lord your God will deliver it over to you, and you must kill every single male by the sword.

14However, the women, little children, cattle, and anything else in the city—all its plunder—you may take for yourselves as spoil. You may take from your enemies the plunder that the Lord your God has given you.

15This is how you are to deal with all those cities located far from you, those that do not belong to these nearby nations.

16As for the cities of these peoples that the Lord your God is going to give you as an inheritance, you must not allow a single living thing to survive.

17Instead you must utterly annihilate them—the Hittites, Amorites, Canaanites, Perizzites, Hivites, and Jebusites—just as the Lord your God has commanded you,

18so that they cannot teach you all the abhorrent ways they worship their gods, causing you to sin against the Lord your God.

19If you besiege a city for a long time while attempting to capture it, you must not chop down its trees, for you may eat fruit from them and should not cut them down. A tree in the field is not human that you should besiege it!

20However, you may chop down any tree you know is not suitable for food, and you may use it to build siege works against the city that is making war with you until that city falls.

1When you go out to battle against your enemies, and see horses, chariots, and a people more than you, you shall not be afraid of them; for Yahweh your God is with you, who brought you up out of the land of Egypt.

2It shall be, when you draw near to the battle, that the priest shall approach and speak to the people,

3and shall tell them, “Hear, Israel, you draw near today to battle against your enemies. Don’t let your heart faint! Don’t be afraid, nor tremble, neither be scared of them;

4for Yahweh your God is he who goes with you, to fight for you against your enemies, to save you.”

5The officers shall speak to the people, saying, “What man is there who has built a new house, and has not dedicated it? Let him go and return to his house, lest he die in the battle, and another man dedicate it.

6What man is there who has planted a vineyard, and has not used its fruit? Let him go and return to his house, lest he die in the battle, and another man use its fruit.

7What man is there who has pledged to be married a wife, and has not taken her? Let him go and return to his house, lest he die in the battle, and another man take her.”

8The officers shall speak further to the people, and they shall say, “What man is there who is fearful and faint-hearted? Let him go and return to his house, lest his brother’s heart melt as his heart.”

9It shall be, when the officers have finished speaking to the people, that they shall appoint captains of armies at the head of the people.

10When you draw near to a city to fight against it, then proclaim peace to it.

11It shall be, if it makes you answer of peace, and opens to you, then it shall be, that all the people who are found therein shall become forced laborers to you, and shall serve you.

12If it will make no peace with you, but will make war against you, then you shall besiege it.

13When Yahweh your God delivers it into your hand, you shall strike every male of it with the edge of the sword;

14but the women, the little ones, the livestock, and all that is in the city, even all its plunder, you shall take for plunder for yourself. You may use the plunder of your enemies, which Yahweh your God has given you.

15Thus you shall do to all the cities which are very far off from you, which are not of the cities of these nations.

16But of the cities of these peoples, that Yahweh your God gives you for an inheritance, you shall save alive nothing that breathes;

17but you shall utterly destroy them: the Hittite, the Amorite, the Canaanite, the Perizzite, the Hivite, and the Jebusite; as Yahweh your God has commanded you;

18that they not teach you to follow all their abominations, which they have done to their gods; so would you sin against Yahweh your God.

19When you shall besiege a city a long time, in making war against it to take it, you shall not destroy its trees by wielding an ax against them; for you may eat of them. You shall not cut them down; for is the tree of the field man, that it should be besieged by you?

20Only the trees that you know are not trees for food, you shall destroy and cut them down. You shall build bulwarks against the city that makes war with you, until it falls.

Summary

God gives laws of warfare — trust Him, not numbers; offer peace first; spare fruit trees — war conducted under God's authority and restraint.

Authorship & Background

Author: Moses. Deuteronomy is the fifth and final book of the Pentateuch, written at the end of the 40 years of wilderness wandering (approximately 1406 BC). Hebrew title: "Devarim" — "Words/Things." Greek title: "Deuteronomion" — "Second Law" (a repetition/expansion of the Law for the new generation). The book consists of Moses' farewell speeches to Israel on the plains of Moab, just before they enter the Promised Land. Moses will not enter with them — these are his final words to the nation he has led for 40 years.
Historical Context: Chapter 20 establishes the laws of warfare — how Israel is to conduct military campaigns in the Promised Land and beyond. The chapter reveals that Israel's warfare is fundamentally different from that of other nations: (1) it begins with a priestly exhortation to trust God, not military might (vv.1-4); (2) it provides generous exemptions for those with unfinished personal obligations (vv.5-8); (3) it requires an offer of peace before attacking distant cities (vv.10-15); (4) it distinguishes between distant cities (where terms are offered) and Canaanite cities (where total destruction is required) (vv.15-18); and (5) it prohibits the destruction of fruit trees during siege (vv.19-20). The opening principle is foundational: "be not afraid of them: for the LORD thy God is with thee" (v.1). Israel's confidence is not in numbers or technology (horses and chariots) but in God's presence. The exemptions (new house, new vineyard, new wife, fearfulness) show that God values human life and personal fulfillment — war is not to consume everything. The distinction between distant and Canaanite cities is crucial: distant cities receive an offer of peace; Canaanite cities receive total destruction because "they teach you not to do after all their abominations" (v.18). The fruit tree prohibition shows remarkable restraint: even in war, God's people must not destroy what sustains life. "The tree of the field is man's life" (v.19 KJV) — creation is not to be wantonly destroyed.
The Priestly Exhortation Before Battle (vv.1-4): "When thou goest out to battle against thine enemies, and seest horses, and chariots, and a people more than thou, be not afraid of them" (v.1). Why? "For the LORD thy God is with thee, which brought thee up out of the land of Egypt" (v.1). The God who defeated Egypt will defeat any enemy. Before battle, the priest speaks: "Hear, O Israel... let not your hearts faint, fear not, and do not tremble, neither be ye terrified" (v.3). Four negatives: no fainting, no fear, no trembling, no terror. Reason: "the LORD your God is he that goeth with you, to fight for you against your enemies, to save you" (v.4). God fights; Israel trusts.
Military Exemptions (vv.5-9): The officers announce four exemptions: (1) "What man is there that hath built a new house, and hath not dedicated it?" — let him go home (v.5). (2) "What man is he that hath planted a vineyard, and hath not yet eaten of it?" — let him go home (v.6). (3) "What man is there that hath betrothed a wife, and hath not taken her?" — let him go home (v.7). (4) "What man is there that is fearful and fainthearted?" — let him go home (v.8). The first three protect personal fulfillment: enjoy what you have built, planted, and committed to. The fourth protects the army: fear is contagious — "lest his brethren's heart faint as well as his heart" (v.8). After exemptions, commanders are appointed (v.9).
Laws for Distant Cities (vv.10-15): "When thou comest nigh unto a city to fight against it, then proclaim peace unto it" (v.10). Peace is offered first. If accepted: the people become tributaries/forced laborers (v.11). If rejected: besiege it (v.12). When God delivers it: "smite every male thereof with the edge of the sword" (v.13). But women, children, livestock, and spoil may be taken (v.14). "Thou shalt eat the spoil of thine enemies, which the LORD thy God hath given thee" (v.14). This applies to "cities which are very far off from thee, which are not of the cities of these nations" (v.15) — non-Canaanite cities.
Laws for Canaanite Cities (vv.16-18): "But of the cities of these people, which the LORD thy God doth give thee for an inheritance, thou shalt save alive nothing that breatheth" (v.16). Total destruction — cherem. "Thou shalt utterly destroy them; namely, the Hittites, and the Amorites, the Canaanites, and the Perizzites, the Hivites, and the Jebusites" (v.17). Why? "That they teach you not to do after all their abominations, which they have done unto their gods; so should ye sin against the LORD your God" (v.18). The purpose is not ethnic hatred but spiritual preservation. Canaanite survival means Canaanite influence means Israelite apostasy.
Protection of Fruit Trees (vv.19-20): "When thou shalt besiege a city a long time... thou shalt not destroy the trees thereof by forcing an axe against them" (v.19). You may eat from them but not cut them down. The remarkable question: "for the tree of the field is man's life" (KJV) / "Are the trees in the field human, that they should be besieged by you?" (ESV) (v.19). Trees are not the enemy — do not wage war on creation. Only non-fruit trees may be cut for siege works (v.20). Even in war, God requires stewardship of creation.

  • Moses speaks from the plains of Moab. Laws of warfare anticipate battles in the Promised Land and against surrounding nations.

Commentary

  • Enduring Word (David Guzik): enduringword.com Guzik emphasizes that Israel's warfare was unique: it began with worship (the priest speaks first, not the general), it provided generous exemptions (God does not need every soldier), and it offered peace first to distant cities. He notes that the Canaanite destruction was not genocide but divine judgment on centuries of accumulated wickedness (Genesis 15:16 — the iniquity of the Amorites was "not yet full").
  • Charles Spurgeon: "'The LORD your God is he that goeth with you.' This is the secret of all courage in spiritual warfare. Not our strength, not our numbers, not our strategy — but His presence. The army that has God in its ranks cannot be defeated. And mark: God does not merely send help — He goes Himself. 'He that goeth with you.' The Commander-in-Chief is personally present on the field."

Reflection

  • 1. "Be not afraid... for the LORD thy God is with thee" (v.1). The foundation of courage is not self-confidence but God-confidence. When the enemy has superior numbers and technology, the question is not "What do we have?" but "Who is with us?" God's presence outweighs every disadvantage.
  • 2. The priest speaks before the general (vv.2-4). Israel's warfare begins with worship, not strategy. The spiritual precedes the military. In spiritual warfare, the same principle applies: prayer and faith precede action. We fight from victory (God's), not for victory (our own).
  • 3. God provides exemptions (vv.5-8). God values human life and personal fulfillment. He does not demand that war consume everything. There is time for houses, vineyards, and marriages. God's kingdom does not require the destruction of ordinary human joys.
  • 4. Fear is contagious (v.8). One fearful person can infect an entire army. This is why God sends the fearful home — not as punishment but as protection for the whole. In the church, chronic fear and unbelief spread to others. Faith must be cultivated and fear addressed.
  • 5. "That they teach you not to do after all their abominations" (v.18). The reason for Canaanite destruction is spiritual, not ethnic. God knows that proximity to idolatry leads to participation in idolatry. The history of Israel proves this: every time they failed to destroy, they were eventually corrupted (Judges 2-3).
  • 6. "The tree of the field is man's life" (v.19). Even in war, creation must be stewarded. Scorched-earth tactics are forbidden. God cares about trees — how much more about all creation? Environmental stewardship is not modern invention but ancient divine command.
