29 Isn’t my word like fire? says Yahweh; and like a hammer that breaks the rock in pieces? 30 Therefore, behold, I am against the prophets, says Yahweh, who steal my words everyone from his neighbor. 31 Behold, I am against the prophets, says Yahweh, who use their tongues, and say, He says. 32 Behold, I am against those who prophesy lying dreams, says Yahweh, and do tell them, and cause my people to err by their lies, and by their vain boasting: yet I didn’t send them, nor commanded them; neither do they profit this people at all, says Yahweh.

33 When this people, or the prophet, or a priest, shall ask you, saying, What is the burden of Yahweh? Then you shall tell them, What burden! I will cast you off, says Yahweh. 34 As for the prophet, and the priest, and the people, who shall say, The burden of Yahweh, I will even punish that man and his house.

Matthew Henry's Commentary on Jeremiah 23:29-34

Commentary on Jeremiah 23:23-32

(Read Jeremiah 23:23-32)

Men cannot be hidden from God's all-seeing eye. Will they never see what judgments they prepare for themselves? Let them consider what a vast difference there is between these prophecies and those delivered by the true prophets of the Lord. Let them not call their foolish dreams Divine oracles. The promises of peace these prophets make are no more to be compared to God's promises than chaff to wheat. The unhumbled heart of man is like a rock; if not melted by the word of God as a fire, it will be broken to pieces by it as a hammer. How can they be long safe, or at all easy, who have a God of almighty power against them? The word of God is no smooth, lulling, deceitful message. And by its faithfulness it may certainly be distinguished from false doctrines.

Commentary on Jeremiah 23:33-40

(Read Jeremiah 23:33-40)

Those are miserable indeed who are forsaken and forgotten of God; and men's jesting at God's judgments will not baffle them. God had taken Israel to be a people near to him, but they shall now be cast out of his presence. It is a mark of great and daring impiety for men to jest with the words of God. Every idle and profane word will add to the sinner's burden in the day of judgment, when everlasting shame will be his portion.
