Twice in Matthew's Gospel the words "bind" [TEXT NOT REPRODUCIBLE IN ASCII] and "loose" [TEXT NOT REPRODUCIBLE IN ASCII] occur in what is apparently a formula that the readers are expected to recognize: * (Jesus says to Peter), "I will give you the keys of the kingdom of heaven, and whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven" (Matt 16:19).
