Leviticus

Thou shalt sanctify him therefore; for he offereth the bread of thy God: he shall be holy unto thee: for I the Lord, which sanctify you, am holy.

Speak thou also unto the children of Israel, saying, Verily my sabbaths ye shall keep: for it is a sign between me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you.

And he said, Peaceably: I am come to sacrifice unto the Lord: sanctify yourselves, and come with me to the sacrifice. And he sanctified Jesse and his sons, and called them to the sacrifice.

Neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwellingplaces, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
