'Valley gate' in the Bible

So I went forth through the valley-gate by night, even unto the front of the snake-fountain, and into the dung-gate, - and I viewed the walls of Jerusalem, how, they, were broken down, and, the gates thereof, consumed with fire.

Then went I up in the torrent-bed, by night, and viewed the wall, - and turned back, and entered by the valley-gate, and so returned.

The valley-gate, did Hanun and the inhabitants of Zanoah, repair, - they, built it, and set up the doors thereof, the locks thereof, and the bars thereof, - also a thousand cubits in the wall, as far as the dung-gate.
