'Valley gate' in the Bible

And Uzziah built towers in Jerusalem at the Corner Gate, at the Valley Gate, and at the Angle, and he strengthened them.

So I went up by the valley during the night and was examining the wall. Then I returned and came to the Valley Gate and returned.

Hanun and the inhabitants of Zanoah repaired the Valley Gate. They rebuilt it and erected its doors, its bolts, and its bars, and a thousand cubits of the wall up to the Dung Gate.
