2 Kings 18:17 ESV

[17] And the king of Assyria sent the Tartan, the Rab-saris, and the Rabshakeh with a great army from Lachish to King Hezekiah at Jerusalem. And they went up and came to Jerusalem. When they arrived, they came and stood by the conduit of the upper pool, which is on the highway to the Washer's Field.
