Leviticus 14:10-13

“And on the eighth day he shall take two male lambs without blemish, one ewe lamb of the first year without blemish, three-tenths of an ephah of fine flour mixed with oil as a grain offering, and one log of oil. Then the priest who makes him clean shall present the man who is to be made clean, and those things, before the LORD, at the door of the tabernacle of meeting. And the priest shall take one male lamb and offer it as a trespass offering, and the log of oil, and wave them as a wave offering before the LORD. Then he shall kill the lamb in the place where he kills the sin offering and the burnt offering, in a holy place; for as the sin offering is the priest’s, so is the trespass offering. It is most holy.
