Alma 55:2

And he said, Behold, I will not exchange prisoners with Ammoron, save he will withdraw his purpose, as I have stated in my epistle; for I will not grant unto him that he shall have any more power than what he hath got.

He said: I will not trade prisoners with Ammoron unless he stops his war plan like I said in my letter. I will not let him have any more power than what he has now.

Moroni said, “I won’t exchange a single prisoner with Ammoron unless he pulls back his forces, just as I said in my letter. I won’t give him any more power than he already has.”
