Matthew 18:15-17 Common English Bible (CEB)
Sinning brother or sister
15 “If your brother or sister sins against you, go and correct them when you are alone together. If they listen to you, then you’ve won over your brother or sister. 16 But if they won’t listen, take with you one or two others so that every word may be established by the mouth of two or three witnesses.[a] 17 But if they still won’t pay attention, report it to the church. If they won’t pay attention even to the church, treat them as you would a Gentile and tax collector.
