"And the priest shall bring it unto the altar, and wring off his head, and burn it on the altar; and the blood thereof shall be wrung out at the side of the altar. "And he shall pluck away his crop with his feathers, and cast it beside the altar, on the east part, by the place of the ashes. "And he shall cleave it with the wings thereof, but shall not divide it asunder: and the priest shall burn it upon the altar, upon the wood that is upon the fire." Here we have a repetition not only of the sacrifice of Abram, but of the mode in which it was offered, care being taken that the body of the bird should not be divided. There is a slight, though not very important variation in one or two portions of this passage. For example, the wringing off the head of the bird is, literally, pinching off, and had to be done with the thumb nail; and the passage which is by some translators rendered as the crop and the feathers, is by others translated as the crop and its contents--a reading which seems to be more consonant with the usual ceremonial of sacrifice than the other. As a general rule, the pigeon was only sanctioned as a sacrificial animal in case one of more value could not be afforded; and so much care was taken in this respect, that with the exception of the two "sparrows" (_tzipporim_) that were enjoined as part of the sacrifice by which the cleansed leper was received back among the people (Lev. xiv. 4), no bird might be offered in sacrifice unless it belonged to the tribe of pigeons. It was in consequence of the poverty of the family that the Virgin Mary brought two young pigeons when she came to present her new-born Son in the Temple. For those who were able to afford it, the required sacrifice was a lamb of the first year for a burnt-offering, and a young pigeon or Turtle Dove for a sin-offering. But "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." The extraordinary value which all Israelites set upon the first-born son is well known, both parents even changing their own names, and being called respectively the father and mother of Elias, or Joseph, as the case may be. If the parents who had thus attained the summit of their wishes possessed a lamb, or could have obtained one, they would most certainly have offered it in the fulness of their joy, particularly when, as in the case of Mary, there was such cause for rejoicing; and the fact that they were forced to substitute a second pigeon for the lamb is a proof of their extreme poverty.
