and anoint them, as you anointed their father, that they may serve me as priests: and their anointing shall admit them to a perpetual priesthood throughout all generations to come.
This day shall be a day of remembrance for you. You shall celebrate it as a festival to the Lord; throughout your generations you shall observe it as a perpetual ordinance.
You shall put them on your brother Aaron, and on his sons with him, and shall anoint them and ordain them and consecrate them, so that they may serve me as priests.
and you shall gird them with sashes and tie headdresses on them; and the priesthood shall be theirs by a perpetual ordinance. You shall then ordain Aaron and his sons.
It shall be for him and for his descendants after him a covenant of perpetual priesthood, because he was zealous for his God, and made atonement for the Israelites.’ ”
Without father, without mother, without genealogy, having neither beginning of days nor end of life, but resembling the Son of God, he remains a priest forever.
