Matthew 18:18-20 - Prohibiting And Permitting
18 "Truly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. 19 Again I say to you, that if two of you agree on earth about anything they ask, it will be done for them by my Father in heaven. 20 For where two or three are gathered together in my name, there am I in the midst of them."
