Leviticus 5:10-12 New Life Version (NLV)
10 Then he will make the second bird ready for a burnt gift, by following the Law. So the religious leader will pay the price for him for the sin he has done. And he will be forgiven.
11 ‘But if he does not have enough money for two turtle-doves or two young pigeons, he should bring one- tenth part of a basket of fine flour for a sin gift. He should not put oil or special perfume on it, for it is a sin gift. 12 He will bring it to the religious leader, who will take a handful of it as a part to be remembered. And he will burn this part of the flour on the altar with the gifts made by fire to the Lord. It is a sin gift.
