Leviticus 12:6
6 And when the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb of the firsta year for a burnt offering, and a young pigeon, or a turtledove, for a sin offering, unto the door of the tabernacle of the congregation, unto the priest:
Lev. 12:6. "She shall bring a young pigeon or a turtle dove;" which typifies repentance as well as love. Ezekiel 7:16. "They shall be as doves in the valleys, each one mourning for his iniquity." This is a proper sacrifice for original sin that the child brought into the world with it by the parents' means, a sacrifice both for the parents' and children's sin.
