When the anointed for battle addresses the people he speaks in the holy tongue, as it is said, “And it shall be, when you draw near the battle, that the priest shall approach” (Deuteronomy 20:2) this refers to the anointed for battle. “And speak to the people” (ibid) – in the holy tongue. “He shall say to them, “Hear, O Israel, you are about to join battle with your enemy” (vs. “with your enemy” but not against your brother, not Judah against Shimon nor Shimon against Benjamin, that if you fall into their hand they shall have mercy on you, as it is said, “Then the men named above proceeded to take the captives in hand, and with booty they clothed all the naked among them they clothed them and shod them and gave them to eat and drink and anointed them and provide donkeys for all who were failing and brought them to Jericho, the city of palms, back to their kinsmen. Then they returned to Samaria” (II Chronicles 28:15). Rather against your enemies do you march, so that if you fall into their hand they will have no mercy on you. “Let not your courage falter, fear not, and do not tremble or be in dread of them” (Deuteronomy 20: “Let not your courage falter”-- at the neighing of the horses and the brandishing of swords; “Fear not” --at the crash of shields and the tramp of the soldiers shoes; “Do not tremble” -- at the sound of trumpets; “Or be in dread of them” -- at the sound of battle cries. “For it is the Lord your God that goes with you”--they come [relying] upon the might of flesh and blood, but you come [relying] upon the might of the Omnipresent. The Philistines came [relying] upon the power of Goliath (I Samuel 17:4 ff.), but what happened to him in the end? In the end he fell by the sword and they fell with him. The Ammonites came [relying] upon the power of Shobach (II Samuel 10:16-18), but what happened to him in the end? In the end he fell by the sword and they fell with him. But with you it is otherwise, “For it is the Lord your God is that goes with you” this refers to the camp of the ark.

The following do not return home:He who built a gatehouse, a portico or a porch; He who planted four fruit trees or five trees which are not fruit-bearing; He who took back his divorced wife. If a high priest married a widow, or an ordinary priest married a divorcee or a halutzah, or an Israelite married a mamzereth or a netinah, or the daughter of an Israelite married a mamzer or a natin, he does not return home. Rabbi Judah says: even he who builds a house upon its [original] foundations does not return home. Rabbi Eliezer says: even he who builds a brick-house in the Sharon does not return home.

The following do not move from their place: He who built a new house and dedicated it, He who planted a vineyard and used its fruit, He who married his betrothed, Or brought in his yevamah; As it is said, “He shall be exempt one year for the sake of his household [to give happiness to the woman he married]” (Deuteronomy 24:5) “His household,” this refers to his house; “Shall be” refers to his vineyard; “To give happiness to the wife” refers to his wife; “He married” to include his yevamah’s widow. These do not supply water and food and repair the roads [for the army].

“Then the officers shall go on addressing the troops and say, ‘Is there anyone afraid and disheartened’” (Deuteronomy 20:8).Rabbi Akiva says: “afraid and disheartened” is to be understood literally, that he cannot stand in the battle lines and see a drawn sword. Rabbi Yose the Galilean says: “afraid and disheartened” this is the one who is afraid because of the transgressions he has committed; therefore the Torah connected all these [other categories of those who return home] with him that he may return home on their account. Rabbi Yose says: a high priest who married a widow, an ordinary priest who married a divorcee or halutzah, an Israelite who married a mamzeret or netinah, and the daughter of an Israelite who married a mamzer or a natin behold this one is “afraid and disheartened.”

“And it shall be, when the officers have finished speaking to the people, they shall appoint captains of hosts at the head of the people” (Deuteronomy 20:9). And at the rear of the people they station guards in front of them and others behind them, with iron axes in their hands, and should anyone wish to flee, they have permission to strike his thighs, because the beginning of falling [in battle] is fleeing, as it is said, “Israel fled before the Philistines, and the people also suffered a great slaughter” (I Samuel 4:17) and elsewhere it states, “And the men of Israel fled before the Philistines and fell down slain” (ibid 31:1).

To what this apply? To a voluntary war, but in a war commanded [by the Torah] all go out, even a bridegroom from his chamber and a bride from her canopy. Rabbi Judah says: to what does this apply? To a war commanded [commanded by the Torah], but in an obligatory war all go out, even a bridegroom from his chamber and a bride from her canopy.
