Therefore thus saieth the Lord, Behold, I wil visite Shemaiah the Nehelamite, and his seede: hee shall not haue a man to dwell among this people, neither shall he beholde the good, that I will doe for my people, sayth the Lord, because he hath spoken rebelliously against the Lord.
Jeremiah 29:30 Then came the worde of the Lord vnto Ieremiah, saying,
Jeremiah 29:31 Send to all them of the captiuitie, saying, Thus saith the Lord of Shemaiah the Nehelamite, Because that Shemaiah hath prophecied vnto you, and I sent him not, and hee caused you to trust in a lye,
Jeremiah 29:32 Therefore thus saieth the Lord, Behold, I wil visite Shemaiah the Nehelamite, and his seede: hee shall not haue a man to dwell among this people, neither shall he beholde the good, that I will doe for my people, sayth the Lord, because he hath spoken rebelliously against the Lord.
The verse centers on "therefore", "thus", "saieth", "lord", "behold", "visite", "shemaiah", and "nehelamite". It is saying that the verse draws attention to "therefore" and "thus", so its meaning should be read from those terms before moving to application.
The prior verse says "Send to all them of the captiuitie...", giving immediate footing for "therefore" and "thus". In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "thus" with trust shaped by these words, not by a vague optimism outside the passage.
