The priest's exhortation to encourage the people to battle.
Deuteronomy 20:1 When thou goest out to battle against thy 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, who brought thee out of the land of Egypt. Deuteronomy 20:2 And it shall be when ye are come nigh to the battle, that the priest shall approach and speak to the people, Deuteronomy 20:3 And shall say to them, Hear, O Israel, ye approach this day to battle against your enemies: let not your hearts faint, fear not, and do not tremble, neither be ye terrified because of them; Deuteronomy 20:4 For the LORD your God [is] he that goeth with you, to fight for you against your enemies, to save you.
The officers' proclamation who are to be dismissed from the war.
Deuteronomy 20:5 And the officers shall speak to 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 should die in the battle, and another man should dedicate it. Deuteronomy 20:6 And what man [is he] that hath planted a vineyard, and hath not [yet] eaten of it? let him [also] go and return to his house, lest he should die in the battle, and another man should eat of it. Deuteronomy 20:7 And what man [is there] that hath betrothed a wife, and hath not taken her? let him go and return to his house, lest he should die in battle, and another man should take her. Deuteronomy 20:8 And the officers shall speak further to the people, and they shall say, What man [is there that is] fearful and faint-hearted? let him go and return to his house, lest his brethren's heart should faint as well as his heart. Deuteronomy 20:9 And it shall be, when the officers have made an end of speaking to the people, that they shall make captains of the armies to lead the people.
How to use the cities that accept or refuse the proclamation of peace.
Deuteronomy 20:10 When thou comest nigh to a city to fight against it, then proclaim peace to it. Deuteronomy 20:11 And it shall be, if it shall make thee answer of peace, and open to thee, then it shall be, [that] all the people [that are] found therein, shall be tributaries to thee, and they shall serve thee. Deuteronomy 20:12 And if it will make no peace with thee, but will make war against thee, then thou shalt besiege it: Deuteronomy 20:13 And when the LORD thy God hath delivered it into thy hands, thou shalt smite every male of it with the edge of the sword: Deuteronomy 20:14 But the women, and the little ones, and the cattle, and all that is in the city, [even] all the spoil of it, shalt thou take to thyself: and thou shalt eat the spoil of thy enemies, which the LORD thy God hath given thee. Deuteronomy 20:15 Thus shalt thou do to all the cities [which are] very distant from thee, which [are] not of the cities of these nations.
What cities must be devoted.
Deuteronomy 20:16 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: Deuteronomy 20:17 But 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: Deuteronomy 20:18 That they may not teach you to do after all their abominations which they have done to their gods; so would ye sin against the LORD your God.
Trees of man's meat must not be destroyed in the siege.
Deuteronomy 20:19 When thou shalt besiege a city a long time in making war against it to take it, thou shalt not destroy the trees of it by forcing an ax 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: Deuteronomy 20:20 Only the trees 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 shall be subdued.
