8 The Master sent a message against Jacob. It landed right on Israel's doorstep. 9 All the people soon heard the message, Ephraim and the citizens of Samaria. But they were a proud and arrogant bunch. They dismissed the message, saying, 10 "Things aren't that bad. We can handle anything that comes. If our buildings are knocked down, we'll rebuild them bigger and finer. If our forests are cut down, we'll replant them with finer trees." 11 So God incited their adversaries against them, stirred up their enemies to attack: 12 From the east, Arameans; from the west, Philistines. They made hash of Israel. But even after that, he was still angry, his fist still raised, ready to hit them again.

Commentary on Isaiah 9:8-21
(Read Isaiah 9:8-21)
Those are ripening apace for ruin, whose hearts are unhumbled under humbling providences. For that which God designs, in smiting us, is, to turn us to himself; and if this point be not gained by lesser judgments, greater may be expected. The leaders of the people misled them. We have reason to be afraid of those that speak well of us, when we do ill. Wickedness was universal, all were infected with it. They shall be in trouble, and see no way out; and when men's ways displease the Lord, he makes even their friends to be at war with them. God would take away those they thought to have help from. Their rulers were the head. Their false prophets were the tail and the rush, the most despicable. In these civil contests, men preyed on near relations who were as their own flesh. The people turn not to Him who smites them, therefore he continues to smite: for when God judges, he will overcome; and the proudest, stoutest sinner shall either bend or break.
