Before · Matthew 18:18–19
18Most certainly I tell you, whatever things you bind on earth will have been bound in heaven, and whatever things you release on earth will have been released in heaven. 19Again, assuredly I tell you, that if two of you will agree on earth concerning anything that they will ask, it will be done for them by my Father who is in heaven.
20For where two or three are gathered together in my name, there I am in the middle of them.”
