Matthew 18:15-17

Sawyer(i) 15 (16:4) But if your brother sins against you, go and reprove him between you and him alone. If he hears you, you have gained your brother. 16 But if he does not hear you, take with you one or two more, that by the mouth of two or three witnesses every word may be established; 17 and if he will not hear them, tell the assembly; and if he will not hear the assembly, let him be to you as a gentile and a publican.
