And thou, son of man, take thee a sharp knife, take thee a barber's rasor, and cause it to pass upon thine head and upon thy beard: then take thee balances to weigh, and divide the hair.
NASB:
"As for you, son of man, take a sharp sword; take and use it as a barber's razor on your head and beard. Then take scales for weighing and divide the hair.
