John Gill Commentary 1 Kings 2:18

"And Bath-sheba said, Well; I will speak for thee unto the king." — 1 Kings 2:18 (ASV)

And Bathsheba said, well
Very well spoken, the thing is good and right:

I will speak for you to the king ;
and use her interest with him, not seeing into his design, but pitying an unfortunate man.
