What is the context?
Isaiah sends the Lord’s answer because Hezekiah has prayed concerning Sennacherib. The king’s boasts about conquest are exposed as a challenge against the Holy One of Israel. Jerusalem’s threatened people are pictured answering their tormentor with contempt.
The Lord then states what the boast ignores: He planned long ago what has now happened. The fortified cities did not fall because Assyria possessed power independent of Him. He knows the king’s movements and rage, and will turn him back as an animal is controlled by a hook and bit.
A sign of renewed ordinary life is given to Hezekiah. The people will eat what grows on its own for two years, then sow, reap and plant vineyards in the third. The surviving remnant of Judah will take root and bear fruit again.
The final promise is specific. The Assyrian king will not enter Jerusalem or carry the announced attack through there. The Lord will defend the city for His own sake and for the sake of His servant David.
How is this passage commonly understood?
Henry’s treatment of the parallel passage and Gill emphasize that Assyria’s actions remain under God’s knowledge and government. Military success gives the king no ground to exalt himself against the One who allowed it.
Both connect the harvest sign with recovery after disruption. Henry considers whether a Sabbath year also explains the second year’s produce; Gill discusses that possibility alongside the interruption caused by invasion. The promise itself describes provision and the return of sowing and reaping.
Gill connects the reference to David with God’s promise concerning David’s descendants and, ultimately, the Messiah. Henry likewise places the rescue in God’s purpose and glory, rather than treating it as a reward earned by Jerusalem’s inhabitants.
Where does this fit in God's plan?
The reference to David reaches back to 2 Samuel 7:12–16, where the Lord promises an enduring house and kingdom. Isaiah’s rescue promise therefore belongs within a history longer than the immediate siege.
Luke 1:30–33 announces that Jesus will receive the throne of His father David and reign over the house of Jacob forever. His kingdom will not end.
This connection follows the promise named in Isaiah and its New Testament continuation. Jerusalem’s rescue is a real event in Judah’s history; the greater hope is the lasting reign God brings through David’s promised Son.
