Gihon

“Take my servants with you,” said the king. “Set my son Solomon on my own mule and take him down to Gihon.

Then Zadok the priest, Nathan the prophet, and Benaiah son of Jehoiada, along with the Cherethites and Pelethites, went down and set Solomon on King David’s mule, and they escorted him to Gihon.

Zadok the priest and Nathan the prophet have anointed him king at Gihon, and they have gone up from there with rejoicing that rings out in the city. That is the noise you hear.

It was Hezekiah who blocked the upper outlet of the Spring of Gihon and channeled it down to the west side of the City of David. And Hezekiah prospered in all that he did.

After this, Manasseh rebuilt the outer wall of the City of David from west of Gihon in the valley to the entrance of the Fish Gate, and he brought it around the hill of Ophel and heightened it considerably. He also stationed military commanders in all the fortified cities of Judah.
