What does Isaiah 37:33 mean?
The Lord has promised rescue to King Hezekiah, sending a message through Isaiah (Isaiah 37:21–22). The Assyrian army (Isaiah 36:1–3) will be turned away (Isaiah 37:29), and a band of survivors will thrive in the land once more (Isaiah 37:32). Much of Judah's population seems to have been taken by the Assyrian invasion, by death or capture. The remainder remains huddled in Jerusalem, alive but vulnerable to Assyria's standard invasion tactic: a siege (Isaiah 36:12–15).Here, God adds even better news to His promise. Sennacherib, the king of Assyria, will never set foot in Jerusalem. He will not shoot a single arrow, carry a single shield, or dig a single fortification against Jerusalem's walls. This will not be a miraculous victory in battle. Rather, the battle will never happen.
It's unclear whether the full force of the Assyrian army ever closed in on Jerusalem. If they did, we have no record of how far preparations for a siege of Jerusalem advanced. Sennacherib's annals—his personal records which are not part of the biblical record—claim he succeed in making Hezekiah a prisoner in Jerusalem. That may mean that the Assyrian forces succeeded in surrounding the city before they were wiped out in a single night (Isaiah 37:36). Either way, they never attacked the city, fulfilling this promise from God.
