2 Chronicles 32:12

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’?

13 Do you not know what I and my fathers have done to all the peoples of the lands? Have the gods of these nations ever been able to deliver their land from my hand?

14 Who among all the gods of these nations that my fathers devoted to destruction has been able to deliver his people from my hand? How then can your God deliver you from my hand?

15 So now, do not let Hezekiah deceive you, and do not let him mislead you like this. Do not believe him, for no god of any nation or kingdom has been able to deliver his people from my hand or from the hand of my fathers. How much less will your God deliver you from my hand!”

16 And the servants of Sennacherib spoke further against the LORD God and against His servant Hezekiah.
