Nehemiah 2:14

Gate of the fountain. This gate was situated at the southeastern corner of the city, opposite the well En-rogel, now called Job’s Well, or Nehemiah’s Well.

The king’s pool. This name appears nowhere else in the Bible. It is not certain whether Nehemiah refers to the Pool of Siloam, which was fed by the Spring of Siloam through Hezekiah’s tunnel (see on 2 Kings 20:20), or the Pool of Solomon, which, according to Josephus (Wars v. 4. 2), was in the lower Kidron Valley. If the Pool of Siloam is meant, Nehemiah must have re-entered the city through the Gate of the Fountain but encountered so much debris in that section of the city that he returned without being able to complete his investigation. In case the Pool of Solomon is meant, then Nehemiah passed by the Gate of the Fountain and encountered an unusual amount of impassable debris in the lower Kidron Valley.
