'Valley gate' in the Bible

Uzziah built and fortified towers in Jerusalem at the Corner Gate, Valley Gate, and at the Angle.

I proceeded through the Valley Gate by night, in the direction of the Well of the Dragons and the Dung Gate, inspecting the walls of Jerusalem that had been breached and its gates that had been destroyed by fire.

I continued up the valley during the night, inspecting the wall. Then I turned back and came to the Valley Gate, and so returned.

Hanun and the residents of Zanoah worked on the Valley Gate. They rebuilt it and positioned its doors, its bolts, and its bars, in addition to working on fifteen hundred feet of the wall as far as the Dung Gate.
