(39) I will bring again the captivity of Elam.--Of the special history of Elam, as distinct from the other provinces of the Persian Empire, history records but little. The mention of Elamites among those who were present at Jerusalem on the day of Pentecost (Acts 2:9) shows that they were a recognised province under the Parthian monarchy, and that Jews had settled among them in large numbers, and so supplies a partial fulfilment of their return from their captivity.

Verse 39. - But... in the latter days; i.e. presumably in the Messianic age. Into the fulfilment of this promise we need not inquire in too prosaic a spirit. It is true that "Elamites" are mentioned among the persons present on the great "day of Pentecost" (Acts 2:9). But this would be a meagre fulfilment indeed. The fact is that, both in the narrative in the Acts and in this prophecy, the Elamites are chiefly mentioned as representatives of the distant and less civilized Gentile nations, and the fulfilment is granted whenever a similar people to the Elamites is brought to the knowledge of the true religion.

49:34-39 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.But it shall come to pass in the latter days,.... Not in the times of Cyrus, when these people enjoyed their liberty, as the Jews and other nations did, freed by him from the Babylonian yoke; which cannot with propriety be called the latter days, being but seventy or eighty years at most after this prophecy; but in the times of the Messiah, often in prophecy called the latter days:

that I will bring again the captivity of Elam, saith the Lord: which was accomplished in a spiritual sense, when some of these people, the Elamites, were converted to Christ, and delivered by him from the captivity of sin and Satan, and were brought into the glorious liberty of the children of God; see Acts 2:9.
