Joel 3:1
1. bring again the captivity—that is, reverse it. The Jews restrict this to the return from Babylon. Christians refer it to the coming of Christ.

Joel 3:3
3. cast lots for my people—that is, divided among themselves My people as their captives by lot. Compare as to the distribution of captives by lot (Ob 11; Na 3:10).
given a boy for . . . harlot—Instead of paying a harlot for her prostitution in money, they gave her a Jewish captive boy as a slave. girl for wine—So valueless did they regard a Jewish girl that they would sell her for a draught of wine.Joel 3:6
6. Grecians—literally, "Javanites," that is, the Ionians, a Greek colony on the coast of Asia Minor who were the first Greeks known to the Jews. The Greeks themselves, however, in their original descent came from Javan (Ge 10:2, 4). Probably the germ of Greek civilization in part came through the Jewish slaves imported into Greece from Ph nicia by traffickers. Eze 27:13 mentions Javan and Tyre as trading in the persons of men.
far from their border—far from Judea; so that the captive Jews were cut off from all hope of return.
