'What is Good' in the Bible

Be strong, and let us put forth our strength, for the sake of our people, and for the sake of the cities of our God, - and let, Yahweh, do, what is good in his own eyes.

And Ornan said unto David, Take it to thee, and let my lord the king do what is good in his own eyes, - see! I have given the oxen for ascending-sacrifices, and, the threshing implements for wood, and the wheat for a meal-offering, - the whole, have I given.
