24 You shall also speak to Shemaiah the Nehelamite, saying, 25 Thus speaks the Lord of hosts, the God of Israel, saying: You have sent letters in your name to all the people who are at Jerusalem, to Zephaniah the son of Maaseiah the priest, and to all the priests, saying, 26 "The Lord has made you priest instead of Jehoiada the priest, so that there should be officers in the house of the Lord over every man who is demented and considers himself a prophet, that you should put him in prison and in the stocks. 27 Now therefore, why have you not reproved Jeremiah of Anathoth who makes himself a prophet to you? 28 For he has sent to us in Babylon, saying, 'This captivity is long; build houses and dwell in them, and plant gardens and eat their fruit.' " 29 Now Zephaniah the priest read this letter in the hearing of Jeremiah the prophet. 30 Then the word of the Lord came to Jeremiah, saying: 31 Send to all those in captivity, saying, Thus says the Lord concerning Shemaiah the Nehelamite: Because Shemaiah has prophesied to you, and I have not sent him, and he has caused you to trust in a lie-- 32 therefore thus says the Lord: Behold, I will punish Shemaiah the Nehelamite and his family: he shall not have anyone to dwell among this people, nor shall he see the good that I will do for My people, says the Lord, because he has taught rebellion against the Lord.

Commentary on Jeremiah 29:20-32

(Read Jeremiah 29:20-32)

Jeremiah foretells judgments upon the false prophets, who deceived the Jews in Babylon. Lying was bad; lying to the people of the Lord, to delude them into a false hope, was worse; but pretending to rest their own lies upon the God of truth, was worst of all. They flattered others in their sins, because they could not reprove them without condemning themselves. The most secret sins are known to God; and there is a day coming when he will bring to light all the hidden works of darkness. Shemaiah urges the priests to persecute Jeremiah. Their hearts are wretchedly hardened who justify doing mischief by having power to do it. They were in a miserable thraldom for mocking the messengers of the Lord, and misusing his prophets; yet in their distress they trespass still more against the Lord. Afflictions will not of themselves cure men of their sins, unless the grace of God works with them. Those who slight the blessings, deserve to lose the benefit of God's word, like Shemaiah. The accusations against many active Christians in all ages, amount to no more than this, that they earnestly counsel men to attend to their true interest and duties, and to wait for the performance of God's promises in his appointed way.
