9 Say to the nations far and wide: "Get ready for war! Call out your best warriors. Let all your fighting men advance for the attack. 10 Hammer your plowshares into swords and your pruning hooks into spears. Train even your weaklings to be warriors. 11 Come quickly, all you nations everywhere. Gather together in the valley." And now, O Lord, call out your warriors! 12 "Let the nations be called to arms. Let them march to the valley of Jehoshaphat. There I, the Lord, will sit to pronounce judgment on them all. 13 Swing the sickle, for the harvest is ripe. Come, tread the grapes, for the winepress is full. The storage vats are overflowing with the wickedness of these people." 14 Thousands upon thousands are waiting in the valley of decision. There the day of the Lord will soon arrive. 15 The sun and moon will grow dark, and the stars will no longer shine.
16 The Lord 's voice will roar from Zion and thunder from Jerusalem, and the heavens and the earth will shake. But the Lord will be a refuge for his people, a strong fortress for the people of Israel. 17 "Then you will know that I, the Lord your God, live in Zion, my holy mountain. Jerusalem will be holy forever, and foreign armies will never conquer her again.

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.
