1 Corinthians 5:1-7 New American Standard Bible (NASB)
5 It is actually reported that there is immorality among you, and immorality of such a kind as does not exist even among the Gentiles, that someone has his father’s wife. 2 [a]You have become [b]arrogant and [c]have not mourned instead, so that the one who had done this deed would be removed from your midst.
3 For I, on my part, though absent in body but present in spirit, have already judged him who has so committed this, as though I were present. 4 In the name of our Lord Jesus, when you are assembled, and [d]I with you in spirit, with the power of our Lord Jesus, 5 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 [e]Jesus.
6 Your boasting is not good. Do you not know that a little leaven leavens the whole lump of dough? 7 Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed.
1 Corinthians 5:1-7 New International Version (NIV)
Dealing With a Case of Incest
5 It is actually reported that there is sexual immorality among you, and of a kind that even pagans do not tolerate: A man is sleeping with his father’s wife. 2 And you are proud! Shouldn’t you rather have gone into mourning and have put out of your fellowship the man who has been doing this? 3 For my part, even though I am not physically present, I am with you in spirit. As one who is present with you in this way, I have already passed judgment in the name of our Lord Jesus on the one who has been doing this. 4 So when you are assembled and I am with you in spirit, and the power of our Lord Jesus is present, 5 hand this man over to Satan for the destruction of the flesh,[a][b] so that his spirit may be saved on the day of the Lord.
6 Your boasting is not good. Don’t you know that a little yeast leavens the whole batch of dough? 7 Get rid of the old yeast, so that you may be a new unleavened batch—as you really are. For Christ, our Passover lamb, has been sacrificed.
