Book of Joel Chapter 3 Vs. 10

The Lord Judges the Nations

 

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

Beat your plowshares... Prepare for war, let all the enemies of God and of his people join together. Let them even call all the tillers of the ground to their assistance, instead of laboring in the field. Let every peasant become a soldier.

and your pruninghooks... Let them turn their agricultural implements into offensive weapons, so that the weak, being well armed, may confidently say, I am strong. Yet, when thus collected and armed, Jehovah will bring down thy mighty ones; for so the clause (in Joel 3:11), should be rendered.

This is the opposite of beat your swords into plowshares. They are to prepare for the great battle. This war would be so great, that all the farmers and husbandmen would have to fight too.

The nations are to beat their farming implements into weapons (Joel 3:10; contrast Isa. 2:4; Mic. 4:3) and assemble for battle (Joel 3:11; cf. Zec. 12:9).
