15 The man who is honoured and responsible is the head, and the prophet who gives false teaching is the tail. 16 For the guides of this people are the cause of their wandering from the right way, and those who are guided by them come to destruction. 17 For this cause the Lord will have no pleasure in their young men, and no pity on their widows and the children without fathers: for they are all haters of God and evil-doers, and foolish words come from every mouth. For all this his wrath is not turned away, but his hand is stretched out still. 18 For evil was burning like a fire; the blackberries and thorns were burned up; the thick woods took fire, rolling up in dark clouds of smoke. 19 The land was dark with the wrath of the Lord of armies: the people were like those who take men's flesh for food.

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.
