'Measuring' in the Bible

And I go out through the gate of the valley by night, and unto the front of the fountain of the dragon, and unto the gate of the dunghill, and I am measuring about the walls of Jerusalem, that are broken down, and its gates consumed with fire.

and I am going up through the brook by night, and am measuring about the wall, and turn back, and come in through the gate of the valley, and turn back.
