Matthew 18:17-20

17But if he refuses to listen to them, tell it to Messiah’s community. And if he refuses to listen even to Messiah’s community, let him be to you as a pagan and a tax collector.

18“Amen, I tell you, whatever you forbid on earth will have been forbidden in heaven and what you permit on earth will have been permitted in heaven.

19Again I say to you, that if two of you agree on earth about anything they may ask, it shall be done for them by My Father in heaven.

20For where two or three are gathered together in My name, there I am in their midst.”
