'Pruning hooks' in the Bible

And He hath judged between the nations, And hath given a decision to many peoples, And they have beat their swords to ploughshares, And their spears to pruning-hooks, Nation doth not lift up sword unto nation, Nor do they learn any more -- war.

For before harvest, when the flower is perfect, And the blossom is producing unripe fruit, Then hath one cut the sprigs with pruning hooks, And the branches he hath turned aside, cut down.

Beat your ploughshares to swords, And your pruning-hooks to javelins, Let the weak say, 'I am mighty.'

And He hath judged between many peoples, And given a decision to mighty nations afar off, They have beaten their swords to ploughshares, And their spears to pruning-hooks, Nation lifteth not up sword unto nation, Nor do they learn war any more.
