'Knife' in the Bible

And thou, son of man, take thee a sharp knife; a barber's razor shalt thou take; and cause it to pass upon thy head and upon thy beard: and thou shalt take balances to weigh, and divide the hair.

A third part shalt thou burn in the fire in the midst of the city, when the days of the siege are fulfilled; and thou shalt take a third part, and smite about it with a knife; and a third part thou shalt scatter to the wind, and I will draw out a sword after them.
