'Captives' in the Bible

When thou goest forth to war against thine enemies, and Jehovah thy God delivereth them into thy hands, and thou hast taken captives of them,

And seest among the captives a beautiful woman, and hast a desire unto her, that thou wouldest have her to thy wife;

I will make mine arrows drunk with blood, and my sword shall devour flesh; and that with the blood of the slain and of the captives, from the beginning of revenges upon the enemy.
