Matthew 18:15-17

Living_Oracles(i) 15 Wherefore, if your brother trespass against you, go and expostulate with him, when you and he are alone together. If he hear you, you have gained your brother; 16 but if he will not hear, take one or two along with you, that by the testimony of two or three witnesses everything may be ascertained. 17 If he despises them, tell the congregation; and if he despise the congregation also, let him be to you as a pagan or a publican.
