'Pruning hooks' in the Bible

And He will judge between the nations,And will mediate [disputes] for many peoples;And they will beat their swords into plowshares and their spears into pruning hooks.Nation will not lift up the sword against nation,And never again will they learn war.

For before the harvest, when the blossom is overAnd the flower becomes a ripening grape,He will cut off the sprigs [without buds] with pruning knives,And [He will] remove and cut away the spreading branches.
