Matthew 18:16-18

New International Version - UK

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] 17} If they still refuse to listen, tell it to the church; and if they refuse to listen even to the church, treat them as you would a pagan or a tax collector.

¹⁸ ‘Truly I tell you, whatever you bind on earth will be^[b] bound in heaven, and whatever you loose on earth will be^[c] loosed in heaven.
