Matthew:18:15-17
akjv@Matthew:18:15 @ Moreover if your brother shall trespass against you, go and tell him his fault between you and him alone: if he shall hear you, you have gained your brother.
akjv@Matthew:18:16 @ But if he will not hear you, then take with you one or two more, that in the mouth of two or three witnesses every word may be established.
akjv@Matthew:18:17 @ And if he shall neglect to hear them, tell it to the church: but if he neglect to hear the church, let him be to you as an heathen man and a publican.
