Thus shalt thou also speak to Shemaiah the Nehelamite, saying,

Wesley's Notes

29:24 Nehelamite - It is probable there was such a place as Nehelam, from whence he was.

King James Translators' Notes

Nehelamite: or, dreamer

Jamieson-Fausset-Brown Bible Commentary

24-32. A second communication which Jeremiah sent to Babylon, after the messenger who carried his first letter had brought a letter from the false prophet Shemaiah to Zephaniah, &c., condemning Jeremiah and reproving the authorities for not having apprehended him.

Nehelamite-a name derived either from his father or from a place: alluding at the same time to the Hebrew meaning, "a dreamer" (compare Jer 29:8).

Matthew Henry's Concise Commentary

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.
