Gihon

The king said to them, “Take with you the servants of your lord, and cause Solomon my son to ride on my own mule, and bring him down to Gihon.

So Zadok the priest, and Nathan the prophet, and Benaiah the son of Jehoiada, and the Cherethites and the Pelethites, went down, and caused Solomon to ride on king David’s mule, and brought him to Gihon.

Zadok the priest and Nathan the prophet have anointed him king in Gihon. They have come up from there rejoicing, so that the city rang again. This is the noise that you have heard.

This same Hezekiah also stopped the upper spring of the waters of Gihon, and brought them straight down on the west side of the city of David. Hezekiah prospered in all his works.

Now after this he built an outer wall to the city of David, on the west side of Gihon, in the valley, even to the entrance at the fish gate; and he encircled Ophel with it, and raised it up to a very great height: and he put valiant captains in all the fortified cities of Judah.
