Deuteronomy 20:14

And they took all the spoil and all the loot, both of man and of beast.

So Moses said to them, “Have you spared all the women?

The men of war had taken plunder, every man for himself.

“So you shall do to Ai and its king just as you did to Jericho and its king; you shall take only its spoil and its cattle as plunder for yourselves. Set an ambush for the city behind it.”

And he said, “You shall not strike them down. Would you strike down those you have taken captive with your sword and with your bow? Set bread and water before them, that they may eat and drink and walk back to their master.”
