Numbers 6:9-11

Thomson(i) 9 And if any one die suddenly by him, the head of his vow will be immediately defiled, he shall therefore shave his head on the day when he is cleansed. On the seventh day it shall be shaved, 10 and on the eighth day he shall bring two turtle doves, or two young pigeons to the priest, to the doors of the tabernacle of the testimony; 11 and the priest shall offer one for a sin offering, and the other for a whole burnt offering; and the priest shall make atonement for him for the failures of which he hath been guilty by the dead.
