'Lord Who Sanctifies' in the Bible

You shall keep My statutes and do them. I am the Lord who sanctifies you.

You shall consecrate him, therefore, for he offers the food of your God; he shall be holy to you; for I the Lord, who sanctifies you, am holy.

Also I gave them My Sabbaths to be a sign between Me and them, that they might know [without any doubt] that I am the Lord who sanctifies them (separates and sets them apart).
