“Then King Sennacherib of Assyria left. He went home, and lived at Nineveh. While he was worshiping in the house of his god Nisroch, his sons Adrammelech and Sharezer killed him with the sword. They escaped into the land of Ararat. His son Esarhaddon succeeded him.”
As far we know, King Sennacherib died in 681 BCE. Thus it might not have been contemporaneous with his sojourn in Judah. In fact, the text does not indicate that. He was killed by 2 of his sons and a 3rd took over. The god Nisroch was an eagle headed human figure that was a favorite of the Assyrians in Nineveh. Nineveh was on the Tigris River about 250 miles north of Babylon, near the modern day city of Mosul. Esarhaddon was the youngest son of the king’s second wife and ruled from 681-669 BCE, after he defeated his brothers who had killed their father.
