2 Chronicles 32:16-18

16 And his servants spoke yet [more] against the LORD God and against his servant Hezekiah.

17 In addition to this, he wrote letters that blasphemed the LORD God of Israel and spoke against him, saying, As the gods of the Gentiles of [other] lands could not deliver their people out of my hand, neither shall the God of Hezekiah deliver his people out of my hand.

18 Then they cried with a loud voice in the Jews' speech unto the people of Jerusalem that [were] on the wall, to make them afraid and to trouble them, that they might take the city.
