Never surely had a man greater opportunity of doing well than Ahaz had, finding things in a good posture, the kingdom rich and strong and religion established; and yet here we have him in these few verses, 1. Wretchedly corrupted and debauched. He had had a good education given him and a good example set him: but parents cannot give grace to their children. All the instructions he had were lost upon him: He did not that which was right in the sight of the Lord (Ch2 28:1), nay, he did a great deal that was wrong, a wrong to God, to his own soul, and to his people; he walked in the way of the revolted Israelites and the devoted Canaanites, made molten images and worshipped them, contrary to the second commandment; nay, he made them for Baalim, contrary to the first commandment. he forsook the temple of the Lord and sacrificed and burnt incense on the hills, as if they would place him nearer heaven, and under every green tree, as if they would signify the protection and influence of heaven by their shade and dropping. To complete his wickedness, as one perfectly divested of all natural affection as well as religion and perfectly devoted to the service and interest of the great enemy of mankind, he burnt his children in the fire to Moloch (Ch2 28:3), not thinking it enough to dedicate them to that infernal fiend by causing them to pass through the fire. See what an absolute sway the prince of the power of the air bears among the children of disobedience. 2. Wretchedly spoiled and made a prey of. When he forsook God, and at a vast expense put himself under the protection of false gods, God, who of right was his God, delivered him into the hands of his enemies, Ch2 28:5. (1.) The Syrians insulted him and triumphed over him, beat him in the field and carried away a great many of his people into captivity. (2.) The king of Israel, though an idolater too, was made a scourge to him, and smote him with a great slaughter. The people suffered by these judgments: their blood was shed, their country wasted, their families ruined; for when they had a good king, though they did corruptly (Ch2 27:2), yet then his goodness sheltered them; but now that they had a bad one all the defence had departed from them and an inundation of judgments broke in upon them. Those that knew not their happiness in the foregoing reign were taught to value it by the miseries of this reign.

Ahaz was twenty years old - For the difficulties in this chronology, see the notes on Kg2 16:2 (note).
