Isaiah 37:5-7

So the officials came to Isaiah, and the prophet responded by sending them back to the king with a message from Yahweh. Hezekiah was not to fear the blasphemous claims of Sennacherib’s underlings. The Lord promised to lead the invading king away from Jerusalem and back to his own country where he would die by the sword. A report placed in Sennacherib’s ear would be the sovereign Lord’s instrument. The lack of reference to the decimation of the Assyrian troops already gathered around Jerusalem (cf. Isaiah 36:2) focuses the promise on the central issue, divine punishment for the king’s blasphemy (cf. Isaiah 14:24-27; Isaiah 31:8).
