Leviticus 5:7-10

“If you can’t afford a lamb, bring as your penalty to GOD for the sin you have committed two doves or two pigeons, one for the Absolution-Offering and the other for the Whole-Burnt-Offering. Bring them to the priest who will first offer the one for the Absolution-Offering: He’ll wring its neck but not sever it, splash some of the blood of the Absolution-Offering against the Altar, and squeeze the rest of it out at the base. It’s an Absolution-Offering. He’ll then take the second bird and offer it as a Whole-Burnt-Offering, following the procedures step-by-step. “In this way, the priest will make atonement for your sin and you’re forgiven.
