Joel 3:8

I will sell your sons and your daughters; give them up into the hands of the Jews, who thereby shall have opportunities of disposing of them as they see good; so you did with my people, so I will recompense you. Into the hand of the children of Judah; to the Jews, the posterity and kindred of those you sold. They shall sell them; either as factors for Nebuchadnezzar or Alexander the Great and his successors, or else as merchants trading on their own account, they shall make this one part of their trade, to sell Grecians, Tyrians, &c. Now though we should not have any particular history that relates the transactions of those people in this kind, yet we may rest assured it was done, since God said it should be done; nor can we expect, or is it necessary it should be, that the Jews should by a conquest of these people bring them captives, and sell them: the Zidonians, Tyrians, and Philistines did not so against the Jews, but they bought particular persons out of the hands of Syrians and Assyrians, who took the Jews captives; so when Tyre, and Zidon, and the Philistines shall be captivated by the Babylonish power, or by the Grecian, these shall sell their captives either into the hands or by the hands of the Jews. Sabeans were a people in the parts of Arabia most remote from Tyre and Zidon; they were accounted the ends of the earth, Matthew 12:42, and spread themselves along by the sea-coast on both sides of the Arabian bay or Red Sea, and passed over that sea, and planted in Africa, and were part of that country which now doth, or lately did belong to the emperor of Abyssinia, who (as the king of Spain in both Indies) glorieth in being king of both Sabeas, and successor to the queen of Sheba; to one or both of these Sabeans did the Jewish men-sellers dispose of those slaves. To a people far off: this may be an elliptic speech, thus to be filled up, and the Sabeans shall sell them (i.e. whom they bought of the Jews) unto another nation far off from the Sabeans; or else it is an additional description of this people and their country, For the Lord hath spoken it; then it was done, whether we know when, or by whom, or how many were sold, or not.
