2 Chronicles 32:8

4 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.

5 Then Hezekiah worked resolutely to rebuild all the broken sections of the wall and to raise up towers on it. He also built an outer wall and reinforced the supporting terraces of the City of David, and he produced an abundance of weapons and shields.

6 Hezekiah appointed military commanders over the people and gathered the people in the square of the city gate. Then he encouraged them, saying,

7 “Be strong and courageous! Do not be afraid or discouraged before the king of Assyria and the vast army with him, for there is a greater One with us than with him.

8 With him is only the arm of flesh, but with us is the LORD our God to help us and to fight our battles.” So the people were strengthened by the words of Hezekiah king of Judah.

9 Later, as Sennacherib king of Assyria and all his forces besieged Lachish, he sent his servants to Jerusalem with a message for King Hezekiah of Judah and all the people of Judah who were in Jerusalem:

10 “This is what Sennacherib king of Assyria says: What is the basis of your confidence, that you remain in Jerusalem under siege?

11 Is not Hezekiah misleading you to give you over to death by famine and thirst when he says, ‘The LORD our God will deliver us from the hand of the king of Assyria?’

12 Did not Hezekiah himself remove His high places and His altars and say to Judah and Jerusalem, ‘You must worship before one altar, and on it you shall burn sacrifices’?
