2 Chronicles 32:1-3

1After Hezekiah had faithfully carried out this work, King Sennacherib of Assyria invaded Judah. He laid siege to the fortified towns, giving orders for his army to break through their walls.

2When Hezekiah realized that Sennacherib also intended to attack Jerusalem,

3he consulted with his officials and military advisers, and they decided to stop the flow of the springs outside the city.
