Charles Ellicott Commentary Zephaniah 3:10

"From beyond the rivers of Ethiopia my suppliants, even the daughter of my dispersed, shall bring mine offering." — Zephaniah 3:10 (ASV)

The daughter of my dispersed. —that is, dropping the Hebrew idiom, “my dispersed people.” Even from the southern limit of the known world will the new Church draw adherents. The “dispersed people” are not Jewish exiles, but the Gentile tribes of the dispersion (Genesis 11:8) which have been previously alienated from their Creator by ignorance and vice. Similarly, Caiaphas prophesies that Christ should not only die for the Jewish nation, but that He should gather together in one the children of God that were scattered abroad (John 11:51–52).

Bring my offering. —The minchâh or bloodless oblation. The phrase here merely represents homage rendered to Jehovah as paramount. So in Malachi 1:11 it is foretold that in every place incense shall be offered to my name, and a pure minchâh. (Malachi 1:11). In Isaiah 66:20, on the other hand, the Gentiles are represented as bringing the dispersed Jews back to Jerusalem as a minchâh to Jehovah (Isaiah 66:20). De Wette and others (wrongly, as we believe), give this passage the same force, rendering, From beyond the rivers of Ethiopia shall men bring my suppliants, even my dispersed people, as my offering.
