Leviticus 21:8

Speak unto all the congregation of the children of Israel, and say unto them, Ye shall be holy: for I the LORD your God am holy.

They shall be holy unto their God, and not profane the name of their God: for the offerings of the LORD made by fire, and the bread of their God, they do offer: therefore they shall be holy.

And for their sakes I sanctify myself, that they also might be sanctified through the truth.

And Moses went down from the mount unto the people, and sanctified the people; and they washed their clothes.

And this is the thing that thou shalt do unto them to hallow them, to minister unto me in the priest’s office: Take one young bullock, and two rams without blemish,

And the LORD said unto Moses, Go unto the people, and sanctify them to day and to morrow, and let them wash their clothes,

Say ye of him, whom the Father hath sanctified, and sent into the world, Thou blasphemest; because I said, I am the Son of God?

And thou shalt put them upon Aaron thy brother, and his sons with him; and shalt anoint them, and consecrate them, and sanctify them, that they may minister unto me in the priest’s office.

Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace?
