He shall slay them before your eyes - Nebuchadnezzar would be led by political reasons to punish these pretended prophets, as their predictions tended to make his Israelitish subjects uneasy and disaffected, and might excite them to rebellion. He therefore slew them; two of them, it appears, he burnt alive, viz., Ahab and Zedekiah, who are supposed by the rabbins to be the two elders who endeavored to seduce Susanna, see Jeremiah 29:23. Burning alive was a Chaldean punishment, Daniel 3:6, and Amos 2:1. From them other nations borrowed it.

Thus saith the Lord of hosts, the God of Israel,.... See Gill on Jeremiah 29:4;

of Ahab the son of Kolaiah, and of Zedekiah the son of Maaseiah, which prophesy a lie unto you: two false prophets, of whom we have no account any where else but here; and are, no doubt, the prophets, or however two of them, that they of the captivity boasted of that God had raised unto them in Babylon, Jeremiah 29:15. The Jews (c) say, and so Jerom relates, that these are the two elders that attempted the chastity of Susannah:

behold, I will deliver them into the hand of Nebuchadrezzar king of Babylon: they should be suffered to commit some crime against the state, of which notice should be given, and they should be seized as seditious persons; which was so permitted in providence, that they might be brought to punishment for other sins they were guilty of:

and he shall slay them before your eyes; by roasting them with fire: as follows:

(c) R. Gedaliah Shalshelet Hakabala, fol. 80. 1.

After having set forth the divine determination, the prophet's letter addresses itself specially against the false prophets and tells them their punishment from God. Jeremiah 29:21. "Thus saith Jahveh, the God of hosts, of Ahab the son of Kolaiah, and of Zedekiah the son of Maaseiah, who prophesy to you in my name falsely: Behold, I give them into the hand of Nebuchadrezzar the king of Babylon, that he may smite them before your eyes. Jeremiah 29:22. And of them shall be taken up a curse by all the exiles of Judah that are in Babylon, saying: Jahveh make thee like Zedekiah and like Ahab, whom the king of Babylon roasted in the fire, Jeremiah 29:23. Because they have done folly in Israel, and have committed adultery with their neighbours' wives, and have spoken in my name lying words which I have not commanded them. But I know it and am witness, saith Jahveh." - Beyond what is here told, we know nothing of these two pseudo-prophets. The name אחאב is written in Jeremiah 29:20 without א; thus the Kametz comes to be under the ח, and in consequence of this the Pathach is changed into a Seghol "Smite," i.e., slay. The manner of their death is called, probably with allusion to the name Kolaiah, קלה, roast, burn in a heated furnace; a mode of execution usual in Babylon, acc. to Daniel 3:6. This punishment is to fall on them because of two kinds of sin: 1. Because they have done folly in Israel, namely, committed adultery with their neighbours' wives; 2. Because they have prophesied falsely in the name of Jahveh. Except in Joshua 7:15, the phrase: commit folly in Israel, is always used of the grosser sins of uncleanness; see on Genesis 34:7. So here also. - The Chet. הוידע is expounded in the Keri by היּודע, according to which there has been a transposition of the letters ו and י, as in Jeremiah 2:25; Jeremiah 8:6, etc. Still the article here is extraordinary, since עד has none. Therefore J. D. Mich., Ew., Hitz., Graf suppose we should read הוּ ידע, the א having been dropped from הוּא in scriptio continua, as it often is, especially after י, in הביא and other words, cf. Jeremiah 19:15; Jeremiah 39:16, 1 Kings 21:29, etc. הוּא is then the copula between subject and predicate, as in Isaiah 43:25; cf. Ew. 297, b.

Thus saith the LORD of hosts, the God of Israel, of Ahab the son of Kolaiah, and of Zedekiah the son of Maaseiah, which prophesy a lie unto you in my name; Behold, I will deliver them into the hand of Nebuchadrezzar king of Babylon; and he shall slay them before your eyes;

21. Zedekiah-brother of Zephaniah (Jer 29:25), both being sons of Maaseiah; probably of the same family as the false prophet under Ahab in Israel (1Ki 22:11, 24).

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.
