'Pruning hooks' in the Bible

And he will judge among the nations, and will rebuke many people: and they shall beat their swords into plow-shares, 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 bud is perfect, and the sour grape is ripening in the flower, he shall both cut off the sprigs with pruning-hooks, and take away and cut down the branches.
