Leviticus 5:10-12 New Living Translation (NLT)
10 The priest will then prepare the second bird as a burnt offering, following all the procedures that have been prescribed. Through this process the priest will purify you from your sin, making you right with the Lord, and you will be forgiven.
11 “If you cannot afford to bring two turtledoves or two young pigeons, you may bring two quarts[a] of choice flour for your sin offering. Since it is an offering for sin, you must not moisten it with olive oil or put any frankincense on it. 12 Take the flour to the priest, who will scoop out a handful as a representative portion. He will burn it on the altar on top of the special gifts presented to the Lord. It is an offering for sin.
