Exodus 29:12, 20, 36

and shall take part of the blood of the bull and put it on the horns of the altar with your finger, and the rest of the blood you shall pour out at the base of the altar.

and you shall kill the ram and take part of its blood and put it on the tip of the right ear of Aaron and on the tips of the right ears of his sons, and on the thumbs of their right hands and on the great toes of their right feet, and throw the rest of the blood against the sides of the altar.

and every day you shall offer a bull as a sin offering for atonement. Also you shall purify the altar, when you make atonement for it, and shall anoint it to consecrate it.
