Levítico 12:8

8 Y si no tiene lo suficiente para un cordero, tomará entonces dos tórtolas o dos palominos, uno como holocausto, y otro como el pecado; y la reconciliará el sacerdote, y será limpia

Levítico 12:8 Meaning and Commentary

Leviticus 12:8

And if she be not able to bring a lamb
As everyone was not in circumstances sufficient to be at the expense of buying a lamb for this purpose, having none of their own:

then she shall bring two turtles, or two young pigeons;
which was a kind and merciful provision for the poorer sort; since it was necessary that by them the favour received should be acknowledged, as well as the sin attending them in such circumstances should be atoned for. This being the offering brought by the mother of our Lord, shows the state of poverty in which she was; and by this, and the circumcision of her child, and the presentation of it before the Lord at the time of her purification, it appears that they were both under the law, and obedient to it:

the one for a burnt offering, and the other for a sin [offering];
Jarchi observes, that in oblations the sin offering goes before the burnt offering, for sin being atoned for, the gift was accepted; but here the burnt offering went first, the reason is not very apparent:

and the priest shall make an atonement for her, and she shall be
clean;
equally the same as if she had brought a lamb, instead of young pigeons, or turtledoves.

Levítico 12:8 In-Context

6 Y cuando los días de su purificación fueren cumplidos, por hijo o por hija, traerá un cordero de un año como holocausto, y un palomino o una tórtola como el pecado, a la puerta del tabernáculo del testimonio, al sacerdote

7 y lo ofrecerá delante del SEÑOR, y la reconciliará, y será limpia del flujo de su sangre. Esta es la ley de la que diere a luz varón o hembra

8 Y si no tiene lo suficiente para un cordero, tomará entonces dos tórtolas o dos palominos, uno como holocausto, y otro como el pecado; y la reconciliará el sacerdote, y será limpia
