Matthew 18:15-18 21st Century King James Version (KJ21)
15 “Moreover, if thy brother shall trespass against thee, go and tell him his fault between thee and him alone. If he shall hear thee, thou hast gained thy brother.
16 But if he will not hear thee, then take with thee one or two more, that ‘in the mouth of two or three witnesses every word may be established.’
17 And if he shall neglect to hear them, tell it unto the church; but if he neglect to hear the church, let him be unto thee as a heathen man and a publican.
18 Verily I say unto you, whatsoever ye shall bind on earth shall be bound in Heaven; and so whatsoever ye shall loose on earth shall be loosed in Heaven.
