Thus saith the Lord, Because, &c. “What was the great sin of Ahab in this action, for which God so severely punished him?” The great dishonour hereby done to God, in suffering so horrid a blasphemer to go unpunished, which was contrary to an express law, Leviticus 24:16. And God had delivered him into Ahab's hand, for his blasphemy, as he promised to do, (1 Kings 20:28,) by which act of his providence, compared with that law, it was most evident that this man was appointed by God to destruction. But Ahab was so far from punishing this blasphemer, that he did not so much as rebuke him, but dismissed him upon easy terms, and took not the least care for the reparation of God's honour. And the people were punished for their own sins, which were many and great; though God took this occasion to inflict the punishment. The former part of this decree of God, Thy life shall go for his life, was fulfilled three years after, when Ahab was killed in a battle against the Syrians, 1 Kings 22:1-40. But the latter, And thy people for his people, was deferred till the reign of Hazael, who fulfilled it by the wars he had with the Israelites, and the slaughter he made of them, 2 Kings 10:32-33.
