הלכה על ויקרא 16:13

The commandment of the sacrifice of the zav when he is healed from his discharge: That the zav offer his sacrifice after he is healed from his discharge, as it is stated (Leviticus 16:13-14), "When the zav is purified from his discharge, etc. And on the eighth day, he shall take two doves, etc." And this sacrifice is two doves or two young pigeons - one for a sin-offering and one for a burnt-offering. And he is called, 'lacking atonement,' until he offers it.
