Zephaniah 3:10

From beyond the rivers of Ethiopia The expression, מעבר, rendered from beyond, may be translated, from the borders of, as it signifies indifferently the hither or further side of a river. In the war with Pharaoh-necho, king of Egypt, many of the Jews were made captive and carried into Egypt, and from thence were sold into Ethiopia, properly so called. This prophecy, therefore, in its primary sense, seems to signify, that the posterity of these, termed here by God the daughter of his dispersed, should bring him an offering, namely, into his temple. And accordingly Cyrus, entering into an alliance with the Ethiopians, obtained that the Jews, who were captives among them, should have their liberty restored to them, that so they might return with others to their own country. In like manner Ptolemy Philadelphus, as Josephus relates, purchased the liberty of a vast number of the Jews, who were captives, or slaves, in very distant countries. Thus were the prophecies of bringing them from the east and the west, and from the north and the south, and from beyond the sea, very remarkably fulfilled. There can be no doubt, however, that this promise ultimately relates to the time when all Israel shall be saved, Romans 11:26; when “the Jews, who are dispersed in the most distant countries, such as was Ethiopia, which lay beyond Egypt, shall come into the Christian Church, and make their religious acknowledgments there.” Lowth.
