Isaiah 9:11-12. “Therefore the Lord shall set up the adversaries of Rezin against him and join his enemies together: The Syrians before, and the Philistines behind: and they shall devour Israel with open mouth. For all this His anger is not turned away, but His hand is stretched out still.”
Rezin, King of Syria, who had attacked Israel, was in turn attacked and conquered by Assyria. Following right behind Rezin was the army of the Philistines. Ephraim, the northern kingdom, had joined Rezin and the Philistines in invading Judah, the southern kingdom Assyria came along and made a clean sweep of all of them. Because of their pride, God allowed them to be swallowed up. His hand was not stretched out in pleading, not any more; now, it was stretched out in anger against Judah and Ephraim, the whole nation of Israel.
I am reminded of Jonathan Edwards sermon, Sinners in the Hands of an Angry God. Israel certainly felt the disciplinary hand of God, and still they persisted in their sin, pride, and idol worship.
