| Barnes' Notes on the Bible Literally, king and princes. Elam will lose its independence, and henceforward have no native ruler with his attendant officers.
Clarke's Commentary on the BibleI will set my throne in Elam - This is spoken either of Nebuchadnezzar or Cyrus. It is certain that Cyrus did render himself master of Elymais and Media, which are in the land of Elam.
Gill's Exposition of the Entire BibleAnd I will set my throne in Elam,.... Either when Alexander subdued it, or Cyrus, or rather Nebuchadnezzar, whose palace probably was, as it is certain his successors was, in Shushan in Elam, as before observed from Daniel 8:2. This is called the Lord's throne, because he gave it to him; his conquest of Elam, and his dominion over it, were from him: and will destroy from thence the king and the princes, saith the Lord; so that there should be no more kings of Elam, and princes and nobles of their own, after this time; and because mention is made of the kings of Elam in the times of Nebuchadnezzar, Jeremiah 25:25; though that is observed in the first year of his reign, some have thought that it is best to understand it or Cyrus, the Lord's servant and anointed; and whose throne might well be called the throne of God, which he gave him, and set him on in an eminent manner, not only there, but elsewhere; see Ezra 1:2; and when this country of Elam, or Elymais, became at part of the Persian empire, and never had any more kings to reign over it separately. Some of the Jewish Rabbins (b), as Kimchi observes, interpret the king and princes of Vashti of Haman and his sons; but very wrongly. (b) In T. Bab. Megillah, fol. 10. 2.
Geneva Study BibleAnd I will set my {i} throne in Elam, and will destroy from there the king and the princes, saith the LORD. (i) I will place Nebuchadnezzar there, and in these prophecies Jeremiah speaks of those countries which would be subdued under the first of those four monarchies of which Daniel makes mention.
Wesley's Notes 49:38 My throne - God calls the throne of Cyrus or Alexander his throne; because he gave it the conqueror.
Jamieson-Fausset-Brown Bible Commentary38. I will show Myself King by My judgments there, as though My tribunal were erected there. The throne of Cyrus, God's instrument, set up over Media, of which Elam was a part, may be meant [Grotius]; or rather, that of Nebuchadnezzar (Jer 43:10). Then the restoration of Elam (Jer 49:39) will refer partly to that which took place on the reduction of Babylon by Cyrus, prince of Persia and Media.
Matthew Henry's Concise Commentary49:34-39 The Elamites were the Persians; they acted against God's Israel, and must be reckoned with. Evil pursues sinners. God will make them know that he reigns. Yet the destruction of Elam shall not be for ever. But this promise was to have its full accomplishment in the days of the Messiah. In reading the Divine assurance of the destruction of all the enemies of the church, the believer sees that the issue of the holy war is not doubtful. It is blessed to recollect, that He who is for us, is more than all against us. And he will subdue the enemies of our souls. |
