Matthew 18:15-20
15 “Moreover, if your brother commits a sin against you, go and show him his fault — but privately, just between the two of you. If he listens to you, you have won back your brother.
16 If he doesn’t listen, take one or two others with you so that every accusation can be supported by the testimony of two or three witnesses.[Deuteronomy 19:15]
17 If he refuses to hear them, tell the congregation; and if he refuses to listen even to the congregation, treat him as you would a pagan or a tax-collector.
18 Yes! I tell you people that whatever you prohibit on earth will be prohibited in heaven, and whatever you permit on earth will be permitted in heaven.
19 To repeat, I tell you that if two of you here on earth agree about anything people ask, it will be for them from my Father in heaven.
20 For wherever two or three are assembled in my name, I am there with them.”
