Exodus 29:11, 16, 20

Then you shall kill the bull before the LORD, by the door of the tabernacle of meeting.

and you shall kill the ram, and you shall take its blood and sprinkle it all around on the altar.

Then you shall kill the ram, and take some of its blood and put it on the tip of the right ear of Aaron and on the tip of the right ear of his sons, on the thumb of their right hand and on the big toe of their right foot, and sprinkle the blood all around on the altar.
