Matthew 18:16-17

New International Version

¹⁶ But if they will not listen, take one or two others along, so that ‘every matter may be established by the testimony of two or three witnesses.’^{[a](A) 17} If they still refuse to listen, tell it to the church;^(B) and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.^(C)
