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.

And gone out again hath the measuring line Over-against it, unto the height of Gareb, And it hath compassed to Goah.

He hath measured the north side, five hundred reeds, with the measuring reed round about.

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