Levítico 12

Y si no alcanzare su mano lo suficiente para un cordero, tomará entonces dos tórtolas ó dos palominos, uno para holocausto, y otro para expiación: y el sacerdote hará expiación por ella, y será limpia.

And if she be not able to bring a lamb, then she shall bring two turtles, or two young pigeons; the one for the burnt offering, and the other for a sin offering: and the priest shall make an atonement for her, and she shall be clean.

If she cannot afford a lamb, then she shall take two turtledoves or two young pigeons: the one for a burnt offering, and the other for a sin offering. The priest shall make atonement for her, and she shall be clean.’”
