'Valley gate' in the Bible

And I went out by night by the valley-gate, even toward the jackal-fountain, and to the dung-gate; and I viewed the walls of Jerusalem, which were in ruins, and its gates were consumed with fire.

And I went up in the night through the valley, and viewed the wall, and turned back, and entered by the valley-gate and returned.

The valley-gate repaired Hanun, and the inhabitants of Zanoah; they built it, and set up its doors, its locks and its bars, and a thousand cubits of the wall as far as the dung-gate.
