“‘Surely no man may consecrate a firstborn that already belongs to the Lord as a firstborn among the animals; whether it is an ox or a sheep, it belongs to the Lord.

“‘If he cannot afford an animal from the flock, he must bring his penalty for guilt for his sin that he has committed, two turtledoves or two young pigeons, to the Lord, one for a sin offering and one for a burnt offering.

If she cannot afford a sheep, then she must take two turtledoves or two young pigeons, one for a burnt offering and one for a sin offering, and the priest is to make atonement on her behalf, and she will be clean.’”
