'What is Good' in the Bible

Be strong, and let us shew ourselves valiant for our people and for the cities of our God; and Jehovah do what is good in his sight.

And the king said to them, I will do what is good in your sight. And the king stood by the gate-side, and all the people came out by hundreds and by thousands.

And he has slandered thy servant to my lord the king; but my lord the king is as an angel of God; do therefore what is good in thy sight.
