'Exchange' in the Bible

And look, all of the family has risen up against your servant, and they said, 'Give up the one who struck his brother, that we may kill him in exchange for the life of his brother whom he murdered. We will also wipe out the heir,' and so they would put out my embers which remain, by not preserving for my husband a name and a remnant on the face of the earth."

and will bring the entire army back to you. In exchange for the life of the man you are seeking, you will get back everyone. The entire army will return unharmed."
