Mateus 18:15-20 - Bíblia Online

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. 
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. 
And if he shall neglect to hear them, tell it to the church: but if he shall neglect to hear the church, let him be to thee as an heathen and a tax collector. 
Verily I say to you, Whatever ye shall bind on earth shall be bound in heaven: and whatever ye shall loose on earth shall be loosed in heaven. 
Again I say to you, That if two of you shall agree on earth concerning any thing that they shall ask, it shall be done for them by my Father who is in heaven. 
For where two or three are gathered together in my name, there am I in the midst of them.
