Numbers 6:10-12

New Century Version

¹⁰ Then on the eighth day, they must bring two doves or two young pigeons to the priest at the entrance to the Meeting Tent. ¹¹ The priest will offer one as a sin offering and the other as a burnt offering. This removes sin so they will belong to the Lord. (They had sinned because they were near a dead body.) That same day they will again promise to let their hair grow ¹² and give themselves to the Lord for another special time. They must bring a male lamb a year old as a penalty offering. The days of the special time before don’t count, because they became unclean during their first special time.
