Numbers 6:10-12

6:10 On the eighth day he is to bring two turtledoves or two young pigeons to the priest, to the entrance to the tent of meeting. 6:11 Then the priest will offer one for a purification offering and the other as a burnt offering, and make atonement for him, because of his transgression in regard to the corpse. So he must reconsecrate his head on that day. 6:12 He must rededicate to the Lord the days of his separation and bring a male lamb in its first year as a reparation offering, but the former days will not be counted because his separation was defiled.
