B. God's judgment on Israel's enemy nations 3:1-17

God's judgment on unbelievers would accompany the spiritual renewal and deliverance of His own in the future day of the Lord. As God promised to wipe out the locusts for despoiling Judah, now He promised to do the same to the nations that had despoiled Judah (cf. Zeph. 3:8; Ezek. 38-39; Matt. 25:31-46).

 1. The announcement of judgment 3:1-8

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.

 2. The description of judgment 3:9-17

This pericope contains a call to the nations to prepare for war (vv. 9-11), a statement by the Lord (vv. 12-13), and a description of the battle site (vv. 14-16).

3:9-11 The Lord issued a call to war. The nations should prepare for a great battle by beating their plowshares into swords and their pruning hooks into spears.³⁴The weak should "psych"themselves up in preparation. The nations should hurry and assemble (cf. Zech. 12:9). Joel also called on Yahweh to bring down His mighty army of angelic warriors to engage the enemy of His people (cf. Deut. 33:2-3; 2 Kings 6:17; Ps. 68:17; 103:19-20; Zech. 14:5).

3:12-13 The Lord urged the nations to rouse themselves and to assemble in the valley of Jehoshaphat (cf. v. 2) because it was there that He would sit in judgment on them. He compared this judgment to harvesting grain with a sickle and to treading grapes in a vat (cf. Isa. 17:5; 63:1-6; Rev. 14:14-20). As grapes squirt juice when trodden, so the nations will give up the wickedness with which they have been full (cf. 2:24).

This scene of divine warfare must correspond to the battle of Armageddon at the end of the Tribulation (cf. Rev. 14:14-20; 16:16; 19:11-21). The judgment of the nations following Christ's second coming (Matt. 25:31-46) will not involve warfare.

3:14-16 The prophet viewed many multitudes in the valley, which he now referred to as the valley of decision because there God will make a decision concerning their fate. This day of the Lord was near from his perspective, which for the prophets was often deceiving due to their foreshortened view of the future. He saw the celestial phenomena again that signaled doom (cf. 2:10, 31). Lion-like Yahweh roared from Zion announcing His attack on the nations, and everything trembled (cf. 2:10-11; Rev. 16:16, 18). For His own people, however, He proved to be a refuge and a stronghold.

3:17 Yahweh's victory will demonstrate to His people that He is indeed Israel's covenant God and that His special place of abode is Mt. Zion (cf. 2:27). After this battle Jerusalem will be the holy city, set apart entirely for God's people and no longer defiled by foreign invaders.
