'Valley gate' in the Bible

And I went out by night by the valley gate, even toward the jackal's well, and to the dung gate, and viewed the walls of Jerusalem, which were broken down, and the gates thereof were consumed with fire.

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

The valley gate repaired Hanun, and the inhabitants of Zanoah; they built it, and set up the doors thereof, the bolts thereof, and the bars thereof, and a thousand cubits of the wall unto the dung gate.
