What does Jeremiah 29:32 mean?

This is what the Lord says: I’ll punish Shemaiah and his family. None of his descendants will live to see the good things I’ll do for my people. He’s preached rebellion against me, says the Lord. Jeremiah 29:32 - Modern Text Bible

(God’s judgment on Shemaiah is severe: his family line will end, and he’ll miss out on the restoration God has promised, because he led people astray.)
