And their king shall go into captivity, he and his princes together, saith the LORD. Their king shall go into captivity - Probably מלכם malcham should be Milcom, who was a chief god of the Ammonites; and the following words, he and his princes, may refer to the body of his priesthood. See 1 Kings 11:33 (note). All these countries were subdued by Nebuchadnezzar.
