Joel 3:10
King James Version
Beat your plowshares into swords and your pruninghooks into spears: let the weak say, I am strong.
Joel 3:10 in context
And I will sell your sons and your daughters into the hand of the children of Judah, and they shall sell them to the Sabeans, to a people far off: for the LORD hath spoken it.
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:
Beat your plowshares into swords and your pruninghooks into spears: let the weak say, I am strong.
Assemble yourselves, and come, all ye heathen, and gather yourselves together round about: thither cause thy mighty ones to come down, O LORD.
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.
