Matthew 18
16 Ref But if he hear `thee' not, take with thee one or two more, that at the mouth of two witnesses or three every word may be established.
17 Ref And if he refuse to hear them, tell it unto the church: and if he refuse to hear the church also, let him be unto thee as the Gentile and the publican.
18 Ref Verily I say unto you, what things soever ye shall bind on earth shall be bound in heaven; and what things soever ye shall loose on earth shall be loosed in heaven.
