1 Corinthians 5:3-5; 1 Corinthians 5:13

3 For I verily, though absent in body but present in spirit, have judged already as though I were present concerning him who hath so done this deed: 4 In the name of our Lord Jesus Christ, when ye are gatheredŒtogether, I being there in spirit, with the power of our Lord Jesus Christ, 5 deliver such a one unto Satan for the destruction of the flesh, that the spirit may be saved in the Day of the Lord Jesus.
13 But those who are outside, God judgeth. Therefore put away from among yourselves that wicked person.
