Exodus 29:12, 20, 36

Use your finger to put some of the bull’s blood on the corners of the altar, and then pour the blood that is left at the bottom of the altar.

Kill it and take some of its blood. Put the blood on the bottom of the right ears of Aaron and his sons and on the thumbs of their right hands and on the big toes of their right feet. Then sprinkle the rest of the blood against all four sides of the altar.

Each day you are to offer a bull to remove the sins of Aaron and his sons so they will be given for service to the LORD. Make the altar ready for service to the LORD, and pour oil on it to make it holy.
