Jeremiah 29:31 “Send a message telling all the exiles what the LORD says concerning Shemaiah the Nehelamite. Because Shemaiah has prophesied to you—though I did not send him—and has made you trust in a lie,
Jeremiah 29:32 this is what the LORD says: ‘I will surely punish Shemaiah the Nehelamite and his descendants. He will have no one left among this people, nor will he see the good that I will bring to My people, declares the LORD, for he has preached rebellion against the LORD.’”
