'Sanctifies' in the Bible

"You are to tell the Israelis: "You are to certainly observe my Sabbaths because it's a sign between me and you from generation to generation, so you may know that I am the LORD who sanctifies you.

Consecrate him, because he's the one who offers the food of your God. He is to be holy for you, because I, the LORD, the one who sanctifies you, am holy.
