Passage
(after that Jeconiah the king, and the queen-mother, and the eunuchs, [and] the princes of Judah and Jerusalem, and the craftsmen, and the smiths, were departed from Jerusalem,)
(after that Jeconiah the king, and the queen-mother, and the eunuchs, [and] the princes of Judah and Jerusalem, and the craftsmen, and the smiths, were departed from Jerusalem,)
Jeremiah 29:1 Now these are the words of the letter that Jeremiah the prophet sent from Jerusalem unto the residue of the elders of the captivity, and to the priests, and to the prophets, and to all the people, whom Nebuchadnezzar had carried away captive from Jerusalem to Babylon,
Jeremiah 29:2 (after that Jeconiah the king, and the queen-mother, and the eunuchs, [and] the princes of Judah and Jerusalem, and the craftsmen, and the smiths, were departed from Jerusalem,)
Jeremiah 29:3 by the hand of Elasah the son of Shaphan, and Gemariah the son of Hilkiah, (whom Zedekiah king of Judah sent unto Babylon to Nebuchadnezzar king of Babylon,) saying,
Jeremiah 29:4 Thus saith Jehovah of hosts, the God of Israel, unto all the captivity, whom I have caused to be carried away captive from Jerusalem unto Babylon:
The verse centers on "after", "jeconiah", "king", "queen-mother", "eunuchs", "princes", "judah", and "jerusalem". It is saying that the verse draws attention to "after" and "jeconiah", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 1's "Now these are the words of the..." into verse 3's "by the hand of Elasah the son...", so "after" and "jeconiah" belong inside that flow. In Jeremiah context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "after" and "jeconiah" with trust shaped by these words, not by a vague optimism outside the passage.
