Matthew 18:18-20 - Prohibiting And Permitting
18 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. 19 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. 20 For where two or three are assembled in my name, there am I in the midst of them.
