Numbers 6:9-11

MLV(i) 9 And if any man dies very suddenly beside him and he defiles the head of his separation, then he will shave his head in the day of his cleansing; on the seventh day he will shave it. 10 And on the eighth day he will bring two turtledoves, or two young pigeons to the priest, to the door of the tent of meeting. 11 And the priest will offer one for a sin offering and the other for a burnt offering and make atonement for him, because he sinned by reason of the dead and will sanctify his head that same day.
