keep alive for yourselves
Both thy bondmen, and thy bondmaids, which thou shalt have, shall be of the heathen that are round about you; of them shall ye buy bondmen and bondmaids.
But 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.
When thou goest forth to war against thine enemies, and the LORD thy God hath delivered them into thine hands, and thou hast taken them captive,
And seest among the captives a beautiful woman, and hast a desire unto her, that thou wouldest have her to thy wife;
Then thou shalt bring her home to thine house; and she shall shave her head, and pare her nails;
And she shall put the raiment of her captivity from off her, and shall remain in thine house, and bewail her father and her mother a full month: and after that thou shalt go in unto her, and be her husband, and she shall be thy wife.
And it shall be, if thou have no delight in her, then thou shalt let her go whither she will; but thou shalt not sell her at all for money, thou shalt not make merchandise of her, because thou hast humbled her.
2 Chronicles 28:8-10
And the children of Israel carried away captive of their brethren two hundred thousand, women, sons, and daughters, and took also away much spoil from them, and brought the spoil to Samaria.
But a prophet of the LORD was there, whose name was Oded: and he went out before the host that came to Samaria, and said unto them, Behold, because the LORD God of your fathers was wroth with Judah, he hath delivered them into your hand, and ye have slain them in a rage that reacheth up unto heaven.
And now ye purpose to keep under the children of Judah and Jerusalem for bondmen and bondwomen unto you: but are there not with you, even with you, sins against the LORD your God?
And the people shall take them, and bring them to their place: and the house of Israel shall possess them in the land of the LORD for servants and handmaids: and they shall take them captives, whose captives they were; and they shall rule over their oppressors.
