Levítico 12:8

8 »Si a la mujer no le alcanza para comprar un cordero, deberá llevar un par de tórtolas o dos pichones de paloma. Uno será para la ofrenda quemada y el otro para la ofrenda de purificación. El sacerdote los sacrificará para purificarla a ella, y quedará ceremonialmente pura».

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 »Cuando se cumpla el tiempo de la purificación, ya sea por haber tenido un hijo o una hija, la mujer deberá llevar un cordero de un año como ofrenda quemada y un pichón de paloma o una tórtola como ofrenda de purificación. Deberá llevar sus ofrendas al sacerdote a la entrada del tabernáculo.

7 Luego el sacerdote las presentará al Señor
para purificarla.
Entonces ella volverá a estar ceremonialmente pura después del flujo de sangre del parto. Estas son las instrucciones para una mujer después del nacimiento de un hijo o una hija.

8 »Si a la mujer no le alcanza para comprar un cordero, deberá llevar un par de tórtolas o dos pichones de paloma. Uno será para la ofrenda quemada y el otro para la ofrenda de purificación. El sacerdote los sacrificará para purificarla a ella, y quedará ceremonialmente pura».
