The record of the pagan Assyrian king Sennacherib, who challenged יהוה, the LORD God of Israel, is found in three biblical texts: 2 Kings 18-19, 2 Chronicles 32 and Isaiah 37. The year was 701 BC. Israel to the north had already fallen to the Assyrians (722 BC). Now (at the time referenced in the above texts) only tiny Judah remained, with its King Hezekiah. At this point Sennacherib had taken forty-six fortified cities of Judah, lastly Lachish, and then came to Jerusalem “with a great army” (Isa. 36:2).
Sennacherib sent the Rabshakeh with the message to Jerusalem, who shouted out in Hebrew, “Hear the word of the great king, the king of Assyria. Thus says the king, Do not let Hezekiah deceive you, for he will not be able to deliver you from my hand; nor let Hezekiah make you trust in the LORD, saying, The LORD will surely deliver us, and this city will not be given into the hand of the king of Assyria.” Then it got worse: “But do not listen to Hezekiah when he misleads you, saying, The LORD will deliver us. Has any one of the gods of the nations delivered his land from the hand of the king of Assyria? Where are the gods of Hamath and Arpad? Where are the gods of Sepharvaim, Hena and Ivvah? Have they delivered Samaria from my hand? Who among all the gods of the lands have delivered their land from my hand, that the LORD should deliver Jerusalem from my hand?” (2 Kings 18:28-30; 32-35).
Hezekiah went to the house of God. He sent for the prophet Isaiah with the request, “Lift up your prayer for the remnant that is left” (2 Kings 19:4). The Lord’s answer: “Whom have you reproached and blasphemed? And against whom have you raised your voice And haughtily lifted up your eyes? Against the Holy One of Israel!” (Isa. 37:23). Further: “Therefore, thus says the LORD concerning the king of Assyria, He will not come to this city or shoot an arrow there; and he will not come before it with a shield, or throw up a siege ramp against it. By the way that he came, by the same he will return, and he will not come to this city, declares the LORD. For I will defend this city to save it for My own sake and for My servant David’s sake. Then the angel of the LORD went out and struck 185,000 in the camp of the Assyrians; and when men arose early in the morning, behold, all of these were dead. So Sennacherib king of Assyria departed and returned home and lived at Nineveh” (vv. 33-37).
One of the fascinating artifacts housed in the British Museum is Sennacherib’s Prism, otherwise known as Taylor’s Prism, named after the one who discovered it. This is King Sennacherib’s account of his victories. He specifically mentions Hezekiah, and the Assyrian siege of Jerusalem.

The text is in Akkadian Cuneiform, the international language of the time. The reference to Hezekiah reads, “
As for Hezekiah, the Judean, I besieged forty-six of his fortified walled cities and surrounding smaller towns, which were without number. Using packed-down ramps and applying battering rams, infantry attacks by mines, breeches, and siege machines, I conquered (them). I took out 200,150 people, young and old, male and female, horses, mules, donkeys, camels, cattle, and sheep, without number, and counted them as spoil. He himself, I locked up within Jerusalem, his royal city, like a bird in a cage.
(Hallo, W. W., & Younger, K. L. (2000). Context of Scripture: Monumental Inscriptions from the Biblical World (p. 303). Leiden; Boston: Brill).
Sennacherib fails to mention why he did not take Jerusalem. He fails to mentions that 185,000 of his Assyrian soldiers died in one night. Why would he say only that he had Hezekiah locked up “like a bird in a cage,” but then fail to go on to record Jerusalem’s capture and that of its king? There can be only one explanation; he failed to do so, just as the Bible says. It is a case when the silence of the Assyrian record speaks volumes. This is after all, the same king who at his palace in Nineveh memorialized his conquest of Lachish with numerous carved stone wall panels which include graphic portrayals of the ramp and siege machines, also housed in the British Museum. But the pagan king did not fare so well when he challenged the LORD, the God of Israel.
