Leviticus 14:21-24

21“If the person is poor and does not have sufficient means, he must take one male lamb as a guilt offering for a wave offering to make atonement for himself, one-tenth of an ephah of choice wheat flour mixed with olive oil for a grain offering, a log of olive oil,

22and two turtledoves or two young pigeons, which are within his means. One will be a sin offering and the other a burnt offering.

23“On the eighth day he must bring them for his purification to the priest at the entrance of the Meeting Tent before the Lord,

24and the priest is to take the male lamb of the guilt offering and the log of olive oil and wave them as a wave offering before the Lord.
