19 By the wrath of the Lord Almighty the land will be scorched and the people will be fuel for the fire; they will not spare one another.
19 Through the wrath of the Lord of hosts the land is scorched, and the people are like fuel for the fire; no one spares another.
19 God-of-the-Angel-Armies answered fire with fire, set the whole country on fire, Turned the people into consuming fires, consuming one another in their lusts -
19 Through the wrath of the Lord of hosts The land is burned up, And the people shall be as fuel for the fire; No man shall spare his brother.
19 The land will be blackened by the fury of the Lord of Heaven's Armies. The people will be fuel for the fire, and no one will spare even his own brother.
Matthew Henry's Commentary on Isaiah 9:19
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.
