And to the angel of the church in Philadelphia say: These things says he who is holy, he who is true, he who has the key of David, opening the door so that it may be shut by no one, and shutting it so that it may be open to no one.

After these things I saw a door open in heaven, and the first voice came to my ears, like the sound of a horn, saying, Come up here, and I will make clear to you the things which are to come.
