The story of King Hezekiah and King Sennacherib, 2 Kings 18-19 and 2 Chronicles 32:1-23. When Sennacherib sent his army to conquer Jerusalem, he sent a message with them: the God of Israel was insignificant. Sennacheribs great sin was unbelief, a direct contrast to Hezekiahs unshakeable belief in the God of Israel. God answered faithful Hezekiahs prayer and sent an angel to destroy the Assyrian army gathered around Jerusalemall 185,000 of them, all at the same time.
