'Pruning hooks' in the Bible

And he will judge between the nations, and will decide concerning many peoples; and they shall beat their swords into plowshares, and their spears into pruning-hooks; nation shall not lift up sword against nation, neither shall they learn war any more.

For before the harvest, when the blossom is over, and the flower becometh a ripening grape, he will cut off the sprigs with pruning-hooks, and the spreading branches will he take away and cut down.

Beat your plowshares into swords, and your pruning-hooks into spears: let the weak say, I am strong.

and he will judge between many peoples, and will decide concerning strong nations afar off: and they shall beat their swords into plowshares, and their spears into pruning-hooks; nation shall not lift up sword against nation, neither shall they learn war any more.
