'Look' in the Bible

And he bowed himself, and said, What is thy servant, that thou shouldest look upon such a dead dog as I am?

And it came to pass in an eveningtide, that David arose from off his bed, and walked upon the roof of the king's house: and from the roof he saw a woman washing herself; and the woman was very beautiful to look upon.

It may be that the LORD will look on mine affliction, and that the LORD will requite me good for his cursing this day.
