You will not fall by the sword

The sword is a metonym for dying in war. Alternate translation: "No one will kill you with their sword" or "You will not die in war" (See: rc://en/ta/man/jit/figs-euphemism and rc://en/ta/man/jit/figs-metonymy)

Your life will be your loot

The word "loot" here is a metaphor for something taken away from Jerusalem after the Babylonians conquer it. This is ironic because the Babylonians would take physical objects, but although the Judeans who surrendered would not die, they would take no physical objects with them. See how you translated a similar phrase in Jeremiah 21:9. Alternate translation: "You will escape with your life" or "You will not die, but you will lose all your possessions" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-irony)
