Jeremiah 27:7

And all nations shall serve him, and his son, and his son's son, until the very time of his land come: and then many nations and great kings shall serve themselves of him.

And all nations shall serve him, and his son, and his son's son - (). Nebuchadnezzar had four successors, Evil-merodach his son; Neriglissar, husband of Nebuchadnezzar's daughter; his son, Labosodarchod; and Naboned (with whom his son Belshazzar was joint king), son of Evil-merodach. But Neriglissar and Labosodarchod were not in the direct male line; so that the prophecy held good to "his son and his son's son," and the intermediate two are omitted.

Until the very time of his land come - i:e., the time of its subjugation, or its being "visited" in wrath (; ; ; ; ; , "MENE: God hath numbered thy kingdom and finished it").

Serve themselves of him - make him their servant (). So "his day" for the destined day of his calamity ().
