1 Corinthians 5:4-7

4When you are assembled in the name of our Lord Jesus1 and I am with you in spirit, along with the power of the Lord Jesus, 5hand this man over to Satan for the destruction of the flesh, so that his spirit may be saved on the Day of the Lord.2

6Your boasting is not good. Do you not know that a little leaven works through the whole batch of dough? 7Get rid of the old leaven, that you may be a new unleavened batch, as you really are. For Christ, our Passover lamb, has been sacrificed.
