Jeremiah 49:39

I will bring again the captivity of Elam - As this is to be in the latter days, probably it may mean the spiritual freedom which these people would receive under the Gospel dispensation. Under Cyrus, the Elamites, collected out of all quarters, were united with the Persians, their neighbors, and became, with them, masters of the east. See Calmet and Dahler. There are still, however, difficulties on this subject. Who the Elamites were is still a question. That which appears to be nearest the truth is, that the Elamites and Persians were two distinct people, and continued so till blended together under Cyrus. It is in this light that I have considered the subject in the preceding notes. Neighboring people are frequently confounded in history, and sometimes the name of a people is given to those who have the same character.

Elam - Elam was subject to Babylon Daniel 8:2, and its capital Shushan a favorite residence of the Persian kings Esther 1:2. Of its subsequent fate we know little; the Elamites continued to exist, and members of their nation were present at Pentecost among those chosen to represent the Gentile world at the first preaching of the Gospel Acts 2:9.

49:39 But - We had the like promise as to Moab, chap. 48:47 , and as to Ammon, ver. 49:6 , the same latter days either signify after many days, or in the time of the Messiah. In the former sense it may refer to Cyrus, who conquered Persia. In the latter sense it refers to the spiritual liberty which some of these poor Heathens were brought into by the gospel. We read Acts 2:9 , that some of the Elamites were at Jerusalem at pentecost, and were some of those converted to Christ.
