1 Corinthians 5
5 Ref That this man is to be handed over to Satan for the destruction of the flesh, so that his spirit may have forgiveness in the day of the Lord Jesus.
6 Ref This pride of yours is not good. Do you not see that a little leaven makes a change in all the mass?
7 Ref Take away, then, the old leaven, so that you may be a new mass, even as you are without leaven. For Christ has been put to death as our Passover.
