Matthew 18:18-20 - Prohibiting And Permitting
18 Truly I say to you, Whatever things ye should bind on earth shall be bound in heaven; and whatever things ye should loose upon earth shall be loosed in heaven. 19 Again, I say to you, That if two of you agree in opinion for everything which they ask, it shall be to them of my Father, he in the heavens. 20 For where two or three are assembled in my name, there am I in the midst of them.
