2 Chronicles 32:4; 2 Chronicles 32:30
A large force of men assembled, and they blocked 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 Gihon spring and channeled the water down to the west side of the City of David. He succeeded in everything he undertook.
