'Valley gate' in the Bible

Moreover, Uzziah built towers in Jerusalem at the Corner Gate and at the Valley Gate and at the corner buttress and fortified them.

So I went out at night by the Valley Gate in the direction of the Dragon’s Well and on to the Refuse Gate, inspecting the walls of Jerusalem which were broken down and its gates which were consumed by fire.

So I went up at night by the ravine and inspected the wall. Then I entered the Valley Gate again and returned.

Hanun and the inhabitants of Zanoah repaired the Valley Gate. They built it and hung its doors with its bolts and its bars, and a thousand cubits of the wall to the Refuse Gate.
