Leviticus 5:11

5:11 "'But if he can't afford two turtledoves, or two young pigeons, then he shall bring his offering for that in which he has sinned, the tenth part of an ephah of fine flour for a sin offering. He shall put no oil on it, neither shall he put any frankincense on it, for it is a sin offering.
