Leviticus 5:9

6 And take to the Lord the offering for the wrong which he has done, a female from the flock, a lamb or a goat, for a sin-offering, and the priest will take away his sin.

7 And if he has not money enough for a lamb, then let him give, for his offering to the Lord, two doves or two young pigeons; one for a sin-offering and one for a burned offering.

8 And let him take them to the priest, who will first give the sin-offering, twisting off its head from its neck, but not cutting it in two;

9 And he is to put drops of the blood of the offering on the side of the altar, and the rest of the blood is to be drained out at the base of the altar; it is a sin-offering.

10 And the second is for a burned offering, in agreement with the law; and the priest will take away his sin and he will have forgiveness.

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.
