'Look' in the Bible

He did obeisance, and said, "What is your servant, that you should look on such a dead dog as I am?"

It happened at evening, that David arose from off his bed, and walked on the roof of the king's house: and from the roof he saw a woman bathing; and the woman was very beautiful to look on.

It may be that Yahweh will look on the wrong done to me, and that Yahweh will repay me good for the cursing of me today."
