2 Chronicles 32:1-3

1 After these things and this faithfulness, Sennacherib king of Assyria came, entered into Judah, and encamped against the fortified cities, and intended to win them for himself.

2 When Hezekiah saw that Sennacherib had come, and that he was planning to fight against Jerusalem,

3 he took counsel with his princes and his mighty men to stop the waters of the springs which were outside of the city, and they helped him.
