Hezekiah prays for help, Sennacherib says not to bother because he always wins, God answers Hezekiah’s prayer: 2 Kings 19:1–19; Isaiah 37:1–20; 2 Chronicles 32:9–19; 2 Kings 19:20–37; Isaiah 37:21–38; 2 Chronicles 32:20–23–22
In response to Sennacherib’s challenge, Isaiah prophesied that the Assyrians would reap what they had sown, and that the king himself would be killed. It happened:
2 Kings 19:35-37 That night the angel of the Lord went out to the Assyrian camp and killed 185,000 Assyrian soldiers. When the surviving Assyrians woke up the next morning, they found corpses everywhere. Then King Sennacherib of Assyria broke camp and returned to his own land. He went home to his capital of Nineveh and stayed there.
One day while he was worshiping in the temple of his god Nisroch, his sons Adrammelech and Sharezer killed him with their swords. They then escaped to the land of Ararat, and another son, Esarhaddon, became the next king of Assyria.
