Leviticus 14:21-23

21And if he be poor, and cannot get so much, then he shall take one he-lamb for a guilt offering to be waved, to make atonement for him, and one tenth part of an ephah of fine flour mingled with oil for a meal offering, and a log of oil;

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 on the eighth day he shall bring them for his cleansing unto the priest, unto the door of the tent of meeting, before the LORD.
