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.
2. queen—Nehushta, the queen mother, daughter of Elnathan (2Ki 24:8, 15). (Elnathan, her father, is perhaps the same as the one mentioned in Jer 26:22). She reigned jointly with her son.
princes—All the men of authority were taken away lest they should organize a rebellion. Jeremiah wrote his letter while the calamity was still recent, to console the captives under it.
