'Knives' in the Bible

He will settle disputes among the nationsand provide arbitration for many peoples.They will turn their swords into plowsand their spears into pruning knives.Nations will not take up the sword against other nations,and they will never again train for war.

For before the harvest, when the season of budding is over, and sour grapes ripen into mature grapes, he cuts off the shoots with pruning knives, clearing away the spreading branches as he lops them off.
