Matthew Henry Commentary Jeremiah 27:19-22

"For thus saith Jehovah of hosts concerning the pillars, and concerning the sea, and concerning the bases, and concerning the residue of the vessels that are left in this city, which Nebuchadnezzar king of Babylon took not, when he carried away captive Jeconiah the son of Jehoiakim, king of Judah, from Jerusalem to Babylon, and all the nobles of Judah and Jerusalem; yea, thus saith Jehovah of hosts, the God of Israel, concerning the vessels that are left in the house of Jehovah, and in the house of the king of Judah, and at Jerusalem: They shall be carried to Babylon, and there shall they be, until the day that I visit them, saith Jehovah; then will I bring them up, and restore them to this place." — Jeremiah 27:19-22 (ASV)

Jeremiah assures them that the brazen vessels would go after the golden ones. All will be carried to Babylon. But he concludes with a gracious promise, that the time would come when they would be brought back. Though the return of the prosperity of the church does not come in our time, we must not despair, for it will come in God's time.
