1 Corinthians 5:4

It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Gentiles, that one has his father’s wife.

You are arrogant, and didn’t mourn instead, that he who had done this deed might be removed from among you.

For I most certainly, as being absent in body but present in spirit, have already, as though I were present, judged him who has done this thing.

you are to deliver such a one to Satan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Jesus.

Your boasting is not good. Don’t you know that a little yeast leavens the whole lump?

Purge out the old yeast, that you may be a new lump, even as you are unleavened. For indeed Christ, our Passover, has been sacrificed in our place.
