1 Corinthians 5:1-7 World English Bible (WEB)
5 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. 2 You are puffed up, and didn’t rather mourn, that he who had done this deed might be removed from among you. 3 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. 4 In the name of our Lord Jesus Christ, you being gathered together, and my spirit, with the power of our Lord Jesus Christ, 5 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.
6 Your boasting is not good. Don’t you know that a little yeast leavens the whole lump? 7 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.
