1 Corinthians 5:1-6

MLV(i) 1 Fornication is heard literally to be among you (and such fornication which is not even named among the Gentiles), that someone has his father’s wife. 2 And you have been arrogant, and did not rather mourn in order that he who did this work might be taken away out of your midst. 3 For indeed, as being absent in the body, but being present in the spirit, I have already judged him thus, who has worked this thing, (as though I am present), 4 in the name of our Lord Jesus Christ. When you and my spirit are gathered together, together with the power of our Lord Jesus, 5 to give such a one to the Adversary for the utter-destruction of the flesh, in order that the spirit might be saved in the day of the Lord Jesus.
6 Your boasting is not good. Do you not know that a little leaven leavens the whole batch?
