Jerusalem: Water Supply Brought in from the Gihon Brook by Hezekiah

Nevertheless, the king of Assyria sent the Tartan, the Rabsaris, and the Rabshakeh, along with a great army, from Lachish to King Hezekiah at Jerusalem. They advanced up to Jerusalem and stationed themselves by the aqueduct of the upper pool, on the road to the Launderer’s Field.

As for the rest of the acts of Hezekiah, along with all his might and how he constructed the pool and the tunnel to bring water into the city, are they not written in the Book of the Chronicles of the Kings of Judah?

…he consulted with his leaders and mighty men about stopping up the waters of the springs outside the city, and they helped him carry it out.

Many people assembled and stopped up all the springs and the stream that flowed through the land. “Why should the kings of Assyria come and find plenty of water?” they said.

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.

So I went out at night through the Valley Gate toward the Well of the Serpent and the Dung Gate, and I inspected the walls of Jerusalem that had been broken down and the gates that had been destroyed by fire. …

Then the LORD said to Isaiah, “Go out with your son Shear-jashub to meet Ahaz at the end of the aqueduct that feeds the upper pool, on the road to the Launderer’s Field,

You saw that there were many breaches in the walls of the City of David. You collected water from the lower pool. …

And the king of Assyria sent the Rabshakeh, with a great army, from Lachish to King Hezekiah at Jerusalem. And he stopped by the aqueduct of the upper pool, on the road to the Launderer’s Field.
