1 Corinthians 5:5-6, 13

I have decided to deliver such a one to Satan for the destruction of his flesh, so that his spirit may be saved in the day of the Lord Jesus. Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough?

But those who are outside, God judges. REMOVE THE WICKED MAN FROM AMONG YOURSELVES.
