Leviticus 14:10-12

10“On the eighth day each person being purified must bring two male lambs and a one-year-old female lamb, all with no defects, along with a grain offering of six quarts of choice flour moistened with olive oil, and a cup of olive oil.

11Then the officiating priest will present that person for purification, along with the offerings, before the Lord at the entrance of the Tabernacle.

12The priest will take one of the male lambs and the olive oil and present them as a guilt offering, lifting them up as a special offering before the Lord.
