*1.* “And to the angel of the church in Philadelphia write:He who is holy, who is true, who has the key of David, who opens and no one will shut, and who shuts and no one opens, says this: ‘I know your deeds. Behold, I have put before you an open door which no one can shut, because you have a little power, and have kept My word, and have not denied My name.”  *2* ““Then I will set the key of the house of David on his shoulder, When he opens no one will shut, When he shuts no one will open.”  *3* “for a wide door for effective service has opened to me, and there are many adversaries.”  *4* “Now when I came to Troas for the gospel of Christ and when a door was opened for me in the Lord.”
