Matthew 18:18-20 - Prohibiting And Permitting
18 Verily I say unto you whatsoever ye bind on earth, shall be bound in heaven. And whatsoever ye loose on earth, shall be loosed in heaven. 19 Again, I say unto you that if two of you shall agree, in earth, upon any manner thing, whatsoever they shall desire; it shall be given them of my father which is in heaven. 20 For where two or three are gathered together in my name, there am I in the midst of them."
