1 Corinthians 5:5-7

Revised Standard Version

⁵ you are to deliver this man to Satan for the destruction of the flesh, that his spirit may be saved in the day of the Lord Jesus.^[a]

⁶ Your boasting is not good. Do you not know that a little leaven leavens the whole lump? ⁷ Cleanse out the old leaven that you may be a new lump, as you really are unleavened. For Christ, our paschal lamb, has been sacrificed.
