'Prisoner' in the Bible

“When you go to war against your enemies and the Lord your God hands them over to you and you take some of them prisoner, and

remove the clothes she was wearing when she was taken prisoner, live in your house, and mourn for her father and mother a full month. After that, you may have sexual relations with her and be her husband, and she will be your wife.

You will father sons and daughters, but they will not remain yours, because they will be taken prisoner.

For the LORD will vindicate his people and bring comfort to his servants, because he will observe that their power has waned, when neither prisoner nor free person remain.
