(21) Yet they ran.--The image is that of messengers who rush eagerly, as from the king's council-chamber, on their self-appointed mission, without waiting for the command of the Master in whose name they profess to come. (Comp. the question, "Who will go for us?" in Isaiah 6:8.)

Verses 21, 22. - In vers. 17-20 Jeremiah has shown that these cannot be true prophets, because their message is diametrically opposed to the true revelation. He now proves it from the absence of any moral effect from their preaching.

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.I have not sent these prophets, yet they ran,.... They might be sent of men, and be encouraged by them; but they were not sent of God: it is not only necessary that men employed in religious affairs should have an external call, in an orderly way, from the church of God; but also an internal call from the Lord himself; he qualifying them with gifts, putting his word into their mouths, and inclining their hearts to publish it; see Hebrews 5:4; but these false prophets had no mission nor commission from the Lord, nor were they sent on any errand, or with any message from him; and

yet they ran; showed great diligence and zeal, and made haste to tell the people what the Lord had never said to them, but what were the warm imaginations of their own heads and hearts; they ran a race or course of ministry, but it was not good, as in Jeremiah 23:10. The Targum adds,

"to do evil:''

I have not spoken to them, yet they prophesied; wherefore what they prophesied was not the word of the Lord, but what they themselves devised; and so was what was false, as the Targum adds: it is a sad character of men when they speak in public neither by the will of God, nor according to the word of God.
