Numbers 6:10-12

Amplified Bible

¹⁰ On the eighth day he shall bring two turtledoves or two young pigeons to the priest, to the doorway of the Tent of Meeting (tabernacle). ¹¹ The priest shall offer the one as a sin offering and the other as a burnt offering and make atonement for him concerning his sin because of the [dead] body. He shall consecrate his head the same day, ¹² and he shall dedicate himself to the Lord for the time of his separation and shall bring a male lamb a year old as a guilt offering; but the previous days will be void and lost, because his separation was defiled.
