2 Chronicles 32:13
Know ye not what I and my fathers have done unto all the people of other lands? were the gods of the nations of those lands any ways able to deliver their lands out of mine hand? Know ye not what I and my fathers have done unto all the people of other lands? were the gods of the nations of those lands any ways able to deliver their lands out of mine hand?
The verse records Sennacherib's boast that he and his fathers had done this to the peoples of other lands by conquering them, and that the gods of those lands had been in no way able to deliver them out of his hand. He used those past victories to argue that Judah's God could not deliver Jerusalem from his power, treating the God of Jerusalem as no greater than powerless human-made idols and making light of Him in order to challenge Judah's confidence in the Lord and discourage Hezekiah. The taunt came with a great display of power against Jerusalem and was repeated with much emphasis in the ears of the people, as proud defiance meant to weaken faith and make God's cause and His people appear mean and insignificant. It is the slur that enemies of truth use as a last resort when legitimate contention fails.
The verse belongs to the history of the kings of Israel and Judah that widens the horizon and presents the setting for Bible events and holds precious spiritual lessons. That history is written not like the boasting proclamations of heathen kings to exalt man but as part of God's historical revelation culminating in Christ, with Christ as the central light holding all its parts together and the Scriptures testifying of Him as wisdom unto salvation and eternal life. In the historical setting of the Assyrian campaign, the Assyrian army was with the king at Libnah, not near Jerusalem, when the angel killed 185,000 men, so this account does not support identifying that destruction with the fulfillment of Isaiah 30:33.
After taking the cities of Judah and sending forces against Jerusalem, his forces were overthrown in one night when, in answer to the humility and prayers of Hezekiah and his people after Hezekiah had cast off the Assyrian yoke, the Lord sent an angel that cut off all the mighty men of valor and the leaders and captains in the camp of the king of Assyria. Sennacherib returned with shame of face to his own land at Nineveh, where he was later killed by his sons while worshiping his idol. This miraculous deliverance of Jerusalem in ignominious defeat of the slur shows that the God of heaven is mightier than the nations and their gods. The lesson's application is that God's people need not use carnal weapons to defend themselves against an armed foe, for their struggle is not against flesh and blood and their weapons are not carnal.
