And you shall not shave a bald spot on your head for the dead, and they shall not shave the side of the beard, and they shall not make cuts in their flesh with cuttings.
They shall be holy to their God, and they shall not profane the name of their God, for they themselves offer the sacrifices of the Lord, the gifts of their God, and they shall be holy.
And he shall sanctify him with the gifts of the Lord your God; this one offers them, he shall be holy, because I am holy, the Lord who sanctifies them.
And the great priest from among his brothers, on whose head the oil of anointing has been poured and who has been consecrated to put on the garments, shall not uncover his head, and he shall not tear his garments.
And he shall not go out from the holy things, and he shall not profane the sanctuary of his God, because the holy oil of the anointing of his God is upon him; I am the Lord
Speak to Aaron: A man from your family throughout your generations, whoever there may be in him a blemish, shall not approach to offer the gifts of his God.
No man of the seed of Aaron the priest in whom there is a blemish shall draw near to offer the sacrifices to your God, because there is a blemish in him; he shall not come near to offer the gifts of God.
Only to the veil he shall not draw near, and to the altar he shall not come near, because he has a blemish; and he shall not profane the holy place of his God, because I am the Lord who sanctifies them.
