Yirmeyah 29:31 Meaning and Commentary

Jeremiah 29:31

Send to all them of the captivity
Another letter; not to Shemaiah, but to the people, that they might all know that he was a false prophet; and how his lies were resented by the Lord; and what punishment should be inflicted on him and his, on account of them: saying, thus saith the Lord concerning Shemaiah the Nehelamite;
the letter, though written by the prophet, must be sent in the name of the Lord, declaring what he would do with the person mentioned, and the reason of it; which follows: because that Shemaiah hath prophesied unto you, and I sent him not,
and he caused you to trust in a lie;
that they should in a very little time return from their captivity to Jerusalem.

32 Therefore thus saith Hashem: Hinei, I will punish Shemaiyah the Nechelami, and his zera; he shall not have an ish to dwell among this people; neither shall he behold the tov that I will do for My people, saith Hashem; because he hath spoken sarah (rebellion) against Hashem.
