'Prisoners' in the Bible

"If you go to battle against your enemies, and the LORD your God delivers them into your control, you may take some prisoners captive.

If you see among the prisoners a beautiful woman and you desire her, then you may take her as your wife.

You will have sons and daughters, but they will not be yours; for they will go away prisoners into a strange land.

I will make my arrows red with blood, my sword will be feasting on flesh, with the blood of the dead and the prisoners, of the long-haired heads of my haters.
