7 And to the Angel of the Church in Philadelphia write, These things saith he that is Holy, he that is true, he that hath the key of Dauid, he that openeth, and no man shutteth, and shutteth, and no man openeth;
8 I know thy workes: behold, I haue set before thee an open doore, and no man can shut it: for thou hast a little strength, and hast kept my word, and hast not denied my Name.
9 Behold, I will make them of the synagogue of Satan, which say they are Iewes, and are not, but doe lie: behold, I will make them to come and worship before thy feete, and to know that I haue loued thee.
10 Because thou hast kept the word of my patience, I also will keepe thee from the houre of temptation, which shall come vpon all the world, to try them that dwell vpon the earth.
11 Beholde, I come quickly, hold that fast which thou hast, that no man take thy crowne.
12 Him that ouercommeth, will I make a pillar in the Temple of my God, and he shall goe no more out: and I wil write vpon him the Name of my God, and the name of the Citie of my God, which is new Hierusalem, which commeth downe out of heauen from my God: And I will write vpon him my New name.
13 Hee that hath an eare, let him heare what the Spirit saith vnto the Churches.
