'Pruning hooks' in the Bible

And he judged between the nations, and he will decide for many peoples: and they shall beat down their swords to plough-shares and their spears to pruning-hooks: nation shall not lift up sword against nation, and they shall no more learn war.

For before the harvest, when the flower was completed, and the sour grape shall be ripening in the flower, and he cut off the shoots with pruning-hooks, and cutting off he took away the tendrils.
