Numbers 6:9-12 - Contingencies For Defilement
9 And if any man dies very suddenly beside him, and he defiles the head of his separation, then he shall shave his head in the day of his cleansing; on the seventh day he shall shave it. 10 And on the eighth day he shall bring two turtle-doves, or two young pigeons to the priest, to the door of the tent of meeting. 11 And the priest shall 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 shall hallow his head that same day. 12 And he shall separate to LORD the days of his separation, and shall bring a he-lamb a year old for a trespass-offering. But the former days shall be void, because his separation was defiled.
