Leviticus 14:21-23

21And if he ispoor, and cannot get so much; then he shall take one lamb for a trespass offering to be waved, to make an atonement for him, and one tenth part of fine flour mixed with oil for a meat offering, and a log of oil;12 22And two turtledoves, or two young pigeons, such as he is able to get; and the one shall be a sin offering, and the other a burnt offering. 23And he shall bring them on the eighth day for his cleansing to the priest, to the door of the tabernacle of the congregation, before the LORD.
