Save you: Good News Translation has “keep you safe” and New Jerusalem Bible “rescue you.”
Fall by the sword: Most versions retain the literal rendering (New Jerusalem Bible “fall to the sword”), but Good News Translation translates “you will not be put to death.” For the first half of the verse, Die Bibel im heutigen Deutsch has “I will protect you so that no one will kill you” and Bible en français courant “I will protect you from death.”
You shall have your life as a prize of war: See 21.9
Says the LORD: For the sake of emphasis, Good News Translation makes this a separate statement and renders “I, the LORD, have spoken.” See 1.8.
