'Look' in the Bible

And John calling unto him two of his disciples sent them to the Lord, saying, Art thou he that cometh, or look we for another?

And when the men were come unto him, they said, John the Baptist hath sent us unto thee, saying, Art thou he that cometh, or look we for another?

And behold, a man from the multitude cried, saying, Teacher, I beseech thee to look upon my son; for he is mine only child:

Look therefore whether the light that is in thee be not darkness.

But when these things begin to come to pass, look up, and lift up your heads; because your redemption draweth nigh.
