1 Corinthians 5:1-6

1 It is actually reported that there is sexual immorality among you, and such sexual immorality as is not even named among the Goyim, 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 assuredly, 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 Yeshua the Messiah, you being gathered together, and my spirit, with the power of our Lord Yeshua the Messiah,
5 are to deliver such a one to Hasatan for the destruction of the flesh, that the spirit may be saved in the day of the Lord Yeshua.
6 Your boasting is not good. Don't you know that a little yeast leavens the whole lump?
