Joel 3:2, 9-16

3:2  I will also gather all nations, and will bring them down into the valley of Jehoshaphat, and will plead with them there for my people and [for] my heritage Israel, whom they have scattered among the nations, and parted my land.

3:9  Proclaim ye this among the Gentiles; Prepare war, wake up the mighty men, let all the men of war draw near; let them come up:

3:10  Beat your plowshares into swords, and your pruninghooks into spears: let the weak say, I [am] strong.

3:11  Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O LORD.

3:12  Let the heathen be wakened, and come up to the valley of Jehoshaphat: for there will I sit to judge all the heathen round about.

3:13  Put ye in the sickle, for the harvest is ripe: come, get you down; for the press is full, the vats overflow; for their wickedness [is] great.

3:14  Multitudes, multitudes in the valley of decision: for the day of the LORD [is] near in the valley of decision.

3:15  The sun and the moon shall be darkened, and the stars shall withdraw their shining.

3:16  The LORD also shall roar out of Zion, and utter his voice from Jerusalem; and the heavens and the earth shall shake: but the LORD [will be] the hope of his people, and the strength of the children of Israel.
