Leviticus 5:11-13 - If You Cannot Afford Two Mourning Doves
11 But if he has not enough money for two doves or two young pigeons, then let him give, for the sin he has done, the tenth part of an ephah of the best meal, for a sin-offering; let him put no oil on it, and no perfume, for it is a sin-offering. 12 And let him come to the priest with it, and the priest will take some of it in his hand, to be burned on the altar as a sign, among the offerings of the Lord made by fire: it is a sin-offering. 13 And the priest will take away his sin and he will have forgiveness: and the rest of the offering will be the priest's, in the same way as the meal offering.
