Leviticus 14:31

one for a sin offering and the other for a burnt offering , along with a grain offering . And the priest shall make atonement before the Lord for him who is being cleansed .

one as a sin offering and the other as a burnt offering, together with the grain offering. In this way the priest will make atonement before the Lord on behalf of the one to be cleansed.”

Even such as he is able to get, the one for a sin offering, and the other for a burnt offering, with the meat offering : and the priest shall make an atonement for him that is to be cleansed before the Lord.
