By the hand of Elasah the son of Shaphan, and Gemariah the son of Hilkiah, (whom Zedekiah king of Judah {c} sent to Babylon to Nebuchadnezzar king of Babylon) saying,

(c) To entreat of some equal condition.

Wesley's Notes

29:3 By the hand - Zedekiah having some occasion to send two messengers to Babylon. Jeremiah knowing that as there were false prophets at Jerusalem, who fed people with hopes of a speedy return, so there were some with them in Babylon, writes the following letter, and sends it by these two messengers, to quiet the peoples minds.

Jamieson-Fausset-Brown Bible Commentary

3. Zedekiah . sent unto Babylon-In Jer 51:59, Zedekiah himself goes to Babylon; here he sends ambassadors. Whatever was the object of the embassy, it shows that Zedekiah only reigned at the pleasure of the king of Babylon, who might have restored Jeconiah, had he pleased. Hence, Zedekiah permitted Jeremiah's letter to be sent, not only as being led by Hananiah's death to attach greater credit to the prophet's words, but also as the letter accorded with his own wish that the Jews should remain in Chaldea till Jeconiah's death.

Hilkiah-the high priest who found the book of the law in the house of the Lord, and showed it to "Shaphan" the scribe (the same Shaphan probably as here), who showed it to King Josiah (2Ki 22:8, &c.). The sons of Hilkiah and Shaphan inherited from their fathers some respect for sacred things. So in Jer 36:25, "Gemariah" interceded with King Jehoiakim that the prophet's roll should not be burned.

Matthew Henry's Concise Commentary

29:1-7 The written word of God is as truly given by inspiration of God as his spoken word. The zealous servant of the Lord will use every means to profit those who are far off, as well as those who are near him. The art of writing is very profitable for this end; and by the art of printing it is rendered most beneficial for circulating the knowledge of the word of God. God's sending to the captives by this letter would show that he had not forsaken them, though he was displeased, and corrected them. If they live in the fear of God, they may live comfortably in Babylon. In all conditions of life, it is our wisdom and duty not to throw away the comfort of what we may have, because we have not all we would have. They are directed to seek the good of the country where they were captives. While the king of Babylon protected them, they must live quiet and peaceable lives under him, in all godliness and honesty; patiently leaving it to God to work deliverance for them in due time.
