“Let The Weak Say, I Am Strong,” Joel 3.

“For behold, in those days and at that time, When I bring back the captives of Judah and Jerusalem, I will also gather all nations, And bring them down to the Valley of Jehoshaphat; And I will enter into judgment with them there On account of My people, My heritage Israel, Whom they have scattered among the nations; They have also divided up My land. Because you have taken My silver and My gold, And have carried into your temples My prized possessions. Also the people of Judah and the people of Jerusalem You have sold to the Greeks, That you may remove them far from their borders. Proclaim this among the nations: “Prepare for war! Wake up the mighty men, Let all the men of war draw near, Let them come up. Beat your plowshares into swords And your pruning hooks into spears; Let the weak say, ‘I am strong.’” “Let the nations be wakened, and come up to the Valley of Jehoshaphat; For there I will sit to judge all the surrounding nations. Multitudes, multitudes in the valley of decision! For the day of the Lord  is near in the valley of decision. The sun and moon will grow dark, And the stars will diminish their brightness. The Lord also will roar from Zion, And utter His voice from Jerusalem; The heavens and earth will shake; But the Lord will be a shelter for His people, And the strength of the children of Israel. “So you shall know that I am the Lord your God, Dwelling in Zion My holy mountain. Then Jerusalem shall be holy, And no aliens shall ever pass through her again.” But Judah shall abide forever, And Jerusalem from generation to generation. For I will acquit them of the guilt of bloodshed, whom I had not acquitted; For the Lord dwells in Zion.”
