John Gill Commentary 1 Kings 20:3

"Thy silver and thy gold is mine; thy wives also and thy children, even the goodliest, are mine." — 1 Kings 20:3 (ASV)

Your silver and your gold is mine: Not of right, but reckoning it as good as in his hands, Ahab not being able to resist him:

and your wives also: for it seems he had more than Jezebel:

and your children: which were many, for he had no less than seventy sons, (2 Kings 10:1) ,

even the goodliest are mine: some aggravate this, as if his view was to commit the unnatural sin with his male children, when in his possession.
