Joel 3:9-12 King James Version (KJV)
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:
10 Beat your plowshares into swords and your pruninghooks into spears: let the weak say, I am strong.
11 Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O Lord.
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.
