'Look' in the Bible

Thou art of purer eyes than to behold evil, and canst not look on mischief: wherefore lookest thou upon them that deal treacherously, and keepest silence when the wicked swalloweth up a man more righteous than he?

I will stand upon my watch, and set me upon the tower, and will look forth to see what he will say unto me, and what I shall answer as to my reproof.

Woe unto him that giveth his neighbour drink, that pourest out thy flask, and makest him drunken also, that thou mayest look on their nakedness!
