Nehemiah 2:13

I went out by night; the footmen which accompanied him directing and leading him in the way. his design was to go round about the city, to observe the compass and condition of the walls and gates, that he might make sufficient provisions for the work. By the gate of the valley; of which see Nehemiah 3:13. Before the dragon well; a fountain of water so called, either from some figure of a dragon or serpent which was by it; or from some living dragon which abode there when the city was desolate; for dragons delight to be in desolate places, and nigh to springs of water, as divers have observed. To the dung-port; through which they used to carry the dung out of the city.
