'Lifted Up His Eyes' in the Bible

Now Absolom had fled. And the young man that was watching lifted up his eyes and looked, and lo! much people, coming on the road behind him, on the mountain-side.

Now, David, was sitting between the two gates, - and the watchman went on to the top of the gate-house, upon the wall, and lifted up his eyes, and looked, and lo! a man, running alone.
