Leviticus 5:11

JPS_ASV_Byz(i) 11 But if his means suffice not for two turtledoves, or two young pigeons, then he shall bring his offering for that wherein he hath sinned, the tenth part of an ephah of fine flour for a sin-offering; he shall put no oil upon it, neither shall he put any frankincense thereon; for it is a sin-offering.
