Leviticus 14:10-12

10On the eighth day he is to bring two unblemished male lambs, an unblemished ewe lamb a year old, a grain offering of three-tenths of an ephah of fine flour1 mixed with olive oil, and one log of olive oil.2 11The priest who performs the cleansing shall present the one to be cleansed, together with these offerings, before the LORD at the entrance to the Tent of Meeting.

12Then the priest is to take one of the male lambs and present it as a guilt offering, along with the log of olive oil; and he must wave them as a wave offering before the LORD.
