Jesus' Words / On Reproving One's Brother
Matthew 18:15–20 · §170
15“If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother. 16But if he doesn’t listen, take one or two more with you, that at the mouth of two or three witnesses every word may be established. 17If he refuses to listen to them, tell it to the assembly. If he refuses to hear the assembly also, let him be to you as a Gentile or a tax collector. 18Most certainly I tell you, whatever things you bind on earth will have been bound in heaven, and whatever things you release on earth will have been released in heaven. 19Again, assuredly I tell you, that if two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven. 20For where two or three are gathered together in my name, there I am in the middle of them.”
15Moreover 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. 16But 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. 17And 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 an heathen man and a publican. 18Verily I say unto you, Whatsoever ye shall bind on earth shall be bound in heaven: and whatsoever ye shall loose on earth shall be loosed in heaven. 19Again I say unto you, That if two of you shall agree on earth as touching any thing that they shall ask, it shall be done for them of my Father which is in heaven. 20For where two or three are gathered together in my name, there am I in the midst of them.
