Nehemiah 2:13

13. The gate of the valley The gate that opened into the valley of Gihon, on the west side of the city, and just at the point where that valley takes a bend off towards the northwest. This would be at the northwestern corner of Zion, where afterwards stood the Tower of Hippicus, erected by Herod.

Before the dragon well The modern upper pool of Gihon, towards which the gate just mentioned must have opened. What gave it this name is now unknown.

The dung port Why our translators rendered the same word port here, which they render gate above, is not apparent. This dung gate is supposed to have been at or near the southwestern corner of the city wall, where the filth and garbage of this part of the city were carried out and thrown down into the deep valley below. See on Nehemiah 3:13.
