'Sanctifying' in the Bible

So Moses slaughtered it, took the blood, and applied some of it at the horns of the altar and around it with his fingers, thus purifying the altar. Then he poured the blood at the base of the altar, thereby sanctifying it as a means to make atonement with it.

and sprinkle it with the blood on his forefinger seven times, cleansing and sanctifying it from Israel's sins."
