Leviticus 5:10-12 Complete Jewish Bible (CJB)
10 He is to prepare the second as a burnt offering in the manner prescribed. Thus the cohen will make atonement for him in regard to the sin which he committed, and he will be forgiven.
(vii) 11 “‘But if his means are insufficient even for two doves or two young pigeons, then he is to bring as his offering for the sin he committed two quarts of fine flour for a sin offering; he is not to put any olive oil or frankincense on it, because it is a sin offering. 12 He is to bring it to the cohen, and the cohen is to take a handful of it as its reminder portion and make it go up in smoke on the altar on top of the offerings for Adonai made by fire; it is a sin offering.
