23:9-22 The false prophets of Samaria had deluded the Israelites into idolatries; yet the Lord considered the false prophets of Jerusalem as guilty of more horrible wickedness, by which the people were made bold in sin. These false teachers would be compelled to suffer the most bitter part of the Lord's indignation. They made themselves believe that there was no harm in sin, and practised accordingly; then they made others believe so. Those who are resolved to go on in evil ways, will justly be given up to believe strong delusions. But which of them had received any revelation of God, or understood any thing of his word? There was a time coming when they would reflect on their folly and unbelief with remorse. The teaching and example of the true prophets led men to repentance, faith, and righteousness. The false prophets led men to rest in forms and notions, and to be quiet in their sins. Let us take heed that we do not follow unrighteousness.
