9 Proclaim this among the nations: Consecrate for war;[1] stir up the mighty men. Let all the men of war draw near; let them come up. 10 Beat your plowshares into swords, and your pruning hooks into spears; let the weak say, "I am a warrior." 11 Hasten and come, all you surrounding nations, and gather yourselves there. Bring down your warriors, O Lord. 12 Let the nations stir themselves up and come up to the Valley of Jehoshaphat; for there I will sit to judge all the surrounding nations. 13 Put in the sickle, for the harvest is ripe. Go in, tread, for the winepress is full. The vats overflow, for their evil is great. 14 Multitudes, multitudes, in the valley of decision! For the day of the Lord is near in the valley of decision. 15 The sun and the moon are darkened, and the stars withdraw their shining.

The Deliverance of Judah

16 The Lord roars from Zion, and utters his voice from Jerusalem, and the heavens and the earth quake. But the Lord is a refuge to his people, a stronghold to the people of Israel. 17 "So you shall know that I am the Lord your God, who dwells in Zion, my holy mountain. And Jerusalem shall be holy, and strangers shall never again pass through it.

Commentary on Joel 3:9-17

(Read Joel 3:9-17)

Here is a challenge to all the enemies of God's people. There is no escaping God's judgments; hardened sinners, in that day of wrath, shall be cut off from all comfort and joy. Most of the prophets foretell the same final victory of the church of God over all that oppose it. To the wicked it will be a terrible day, but to the righteous it will be a joyful day. What cause have those who possess an interest in Christ, to glory in their Strength and their Redeemer! The acceptable year of the Lord, a day of such great favour to some, will be a day of remarkable vengeance to others: let every one that is out of Christ awake, and flee from the wrath to come.
