'Razor' in the Bible

Like a sharpened razor,your tongue devises destruction,working treachery.

On that day the Lord will use a razor hired from beyond the Euphrates River—the king of Assyria—to shave the head, the hair on the legs, and to remove the beard as well.

“Now you, son of man, take a sharp sword, use it as you would a barber’s razor, and shave your head and beard. Then take a set of scales and divide the hair.
