'Blades' in the Bible

And he will be the judge between the nations, and the peoples will be ruled by his decisions: and their swords will be turned into plough-blades, and their spears into vine-knives: no longer will the nations be turning their swords against one another, and the knowledge of war will be gone for ever.

But there the Lord will be with us in his glory, ... wide rivers and streams; where no boat will go with blades, and no fair ship will be sailing.
