'Dung gate' in the Bible

I went out at night through the Valley Gate toward the Serpent’s Well and the Dung Gate, and I inspected the walls of Jerusalem that had been broken down and its gates that had been destroyed by fire.

Hanun and the inhabitants of Zanoah repaired the Valley Gate. They rebuilt it and installed its doors, bolts, and bars, and repaired 500 yards of the wall to the Dung Gate.

Malchijah son of Rechab, ruler over the district of Beth-haccherem, repaired the Dung Gate. He rebuilt it and installed its doors, bolts, and bars.

Then I brought the leaders of Judah up on top of the wall, and I appointed two large processions that gave thanks. One went to the right on the wall, toward the Dung Gate.
