'Look' in the Bible

And I lift up mine eyes, and look, and lo, four horns.

And I lift up mine eyes, and look, and lo, a man, and in his hand a measuring line.

And I turn back, and lift up mine eyes, and look, and lo, a flying roll.

And I turn back, and lift up mine eyes, and look, and lo, four chariots are coming forth from between two of the mountains, and the mountains are mountains of brass.
