'What is Good' in the Bible

And he that was over the house, and he that was over the city, and the elders, and the guardians sent to Jehu, saying, We are thy servants, and will do all that thou shalt bid us; we will not make any one king; do what is good in thy sight.

Ah! Jehovah, remember, I beseech thee, how I have walked before thee in truth and with a perfect heart, and have done what is good in thy sight. And Hezekiah wept much.
