From MCCONNELL 289: "'The Destruction of Sennacherib' is the title of one of the most famous poems of Lord Byron (1788-1824). In II Kings: 19 it is related how the Assyrian King Sennacherib brought a great army to war against the Israelites; but, thanks to the prayers of the Israelites, the Lord killed Sennacherib's whole army in a single night. The legend has an obvious relevance to the sudden, total, and unhoped-for obliteration of the Martian invaders."

From HUGHES AND GEDULD 224: "In a single night, in answer to the prayers of the Israelites, God destroyed the Assyrian army led by King Sennacherib (II Kings 19:35-37). This is the subject of Byron's celebrated poem 'the Destruction of Sennacherib'."

From DANAHAY 182: "reference to II Kings: 19 in which an entire army is wiped out by God in one night"
