Leviticus 5:10-12 Tree of Life Version (TLV)
10 He is to make the second a burnt offering, according to the regulation. So the kohen is to make atonement for one over his sin that he committed—and he will be forgiven.
11 “But if one cannot afford two turtledoves or two young pigeons, then he is to bring as his offering for the sin he has committed a tenth of an ephah[a] of fine flour as a sin offering. He is to put no oil on it nor put any frankincense on it, for it is a sin offering. 12 He is to bring it to the kohen, then the kohen is to take his handful of it as the memorial portion and burn it up as smoke on the altar, on Adonai’s offerings by fire. It is a sin offering.
