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.
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.
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.
Whatever you shall bind on earth shall be bound in heaven: and whatever you shall loose on earth shall be loosed in heaven. (Jesus said these words to Peter in Matthew 16:19. Now Jesus is saying them to all of the apostles.)
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. For where two or three are gathered together in my name, there am I in the midst of them.
Peter: Lord, how often shall my brother sin against me, and I forgive him? till seven times?
Jesus: Not until seven times: but until seventy times seven.
Jesus: If your brother trespass against you, rebuke him; and if he repent, forgive him. And if he trespass against you seven times in a day, and seven times in a day turn again to you, saying, I repent; you shall forgive him.
