When a woman says: "I pledge a pair of doves when I give birth to a male," when she gives birth to a male she must bring four doves: two because of her vow, they are burnt offerings, as we explained, and two which she is obligated to bring because of the birth, one, a burnt-offering and the other, a sin-offering. Therefore the priest must offer three doves on the upper portion of the altar and one dove on the lower portion. If he erred and offered two on the upper portion and two on the lower portion, and he did not consult [with the woman], she must bring another dove and offer it on the upper portion of the altar. When does the above apply? When she brought all four doves from one type; either they were all turtle doves or young doves. If, however, she brought two turtle doves and two young doves and two were offered on the upper portion [of the altar] and two on the lower portion, she must bring one more turtle dove and one more young dove on the upper portion to fulfill her obligation. For if at the outset, two turtle doves were offered on the lower portion, another turtle dove must be brought on the upper portion to complete her obligation. [Or] if two young doves were offered on the lower portion, another young dove must be brought on the upper portion to complete her obligation. For a person should not bring a pair to fulfill his obligation that comprises one turtle dove and one young dove. Instead, either they should both be turtle doves or both be young doves.
