Leviticus 14:24

“If he is poor, and can’t afford so much, then he shall take one male lamb for a trespass offering to be waved, to make atonement for him, and one tenth of an ephah of fine flour mixed with oil for a meal offering, and a log of oil;

and two turtledoves, or two young pigeons, such as he is able to afford; and the one shall be a sin offering, and the other a burnt offering.

“On the eighth day he shall bring them for his cleansing to the priest, to the door of the Tent of Meeting, before the LORD.

He shall kill the lamb of the trespass offering. The priest shall take some of the blood of the trespass offering and put it on the tip 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.

The priest shall pour some of the oil into the palm of his own left hand;

and the priest shall sprinkle with his right finger some of the oil that is in his left hand seven times before the LORD.
