3:1-3 When God would restore the fortunes of Judah and Jerusalem in that future day (cf. Deut. 30:3), He would gather the other nations to the valley of Jehoshaphat (lit. "Yahweh judges"). This is the only passage in Scripture that names the site of this judgment (cf. Zech. 14:3-5). Its exact location is debatable since no valley by this name appears elsewhere in Scripture (cf. vv. 12, 14).32There He would judge them for scattering His covenant people, God's inheritance, and for dividing up His land (cf. Lam. 5:2). They had thought so little of the Hebrews that they gambled for them. They had valued them no higher than the hire of a prostitute or the cost of a drink.
3:4 The Lord addressed the Phoenicians and Philistines directly. They had no special relationship to Yahweh, as Israel did, and they had not been just in dealing with the Israelites. The Lord promised to repay them for their sins. Probably these nations are representative of all Israel's enemies since God said later that He would judge all of them (v. 12).
3:5-6 Specifically these Gentile nations had robbed God and had sold the children of His chosen people as slaves to the Greeks. These nations had stolen from the Israelites. Amos also referred to the Phoenician and Philistine slave trade (Amos 1:6, 9; cf. Ezek. 27:13, 19).
3:7-8 To pay back these nations, the Lord said He would revive the Israelites in the remote places to which they had been sold. The Israelites would grow strong there and would sell the descendants of these Phoenicians and Philistines to the Sabeans (cf. Ezek. 27:22-23). Thus He would pay them back in kind, which is His customary method of retribution (Gal. 6:7). This may have been fulfilled in the fourth century B.C., or the fulfillment may still be future.33Probably the fulfillment lies in the future, specifically the end of the Tribulation, since this whole section of Joel deals with what God will do in that day of the Lord. Again, Phoenicia and Philistia probably represent all the enemies of Israel (cf. Isa. 25:10-12; Obad.) over whom Israel will eventually gain ascendancy.
