Numbers 6:5-7

Good News Translation

⁵ As long as you are under the nazirite vow, you must not cut your hair or shave. You are bound by the vow for the full time that you are dedicated to the Lord, and you shall let your hair grow. ^6-7 Your hair is the sign of your dedication to God, and so you must not defile yourself by going near a corpse, not even that of your father, mother, brother, or sister.
