Leviticus 14:24-25

And the priest shall take the lamb of the guilt offering and the log of oil, and the priest shall wave them for a wave offering before the LORD. And he shall kill the lamb of the guilt offering. And the priest shall take some of the blood of the guilt offering and put it on the lobe of the right ear of him who is to be cleansed, and on the thumb of his right hand and on the big toe of his right foot.
