Matthew 18:15-17 (New International Version)

A Brother Who Sins Against You

 ¹⁵"If your brother sins against you,^[a] go and show him his fault, just between the two of you. If he listens to you, you have won your brother over. ¹⁶But if he will not listen, take one or two others along, so that 'every matter may be established by the testimony of two or three witnesses.'^{[b] 17}If he refuses to listen to them, tell it to the church; and if he refuses to listen even to the church, treat him as you would a pagan or a tax collector.
