“Saying, I am Alpha and Omega, the first and the last: and, What thou seest, write in a book, and send it unto the seven churches which are in Asia; unto Ephesus, and unto Smyrna, and unto Pergamos, and unto Thyatira, and unto Sardis, and unto Philadelphia, and unto Laodicea.”
King James Version (KJV)
1:11 Saying, What thou seest - And hearest. He both saw and heard. This command extends to the whole book. All the books of the New Testament were written by the will of God; but none were so expressly commanded to be written. In a book - So all the Revelation is but one book: nor did the letter to the angel of each church belong to him or his church only; but the whole book was sent to them all. To the churches - Hereafter named; and through them to all churches, in all ages and nations. To Ephesus - Mr. Thomas Smith, who in the year 1671 travelled through all these cities, observes, that from Ephesus to Smyrna is forty - six English miles; from Smyrna to Pergamos, sixty - four; from Pergamos to Thyatira, forty - eight; from Thyatira to Sardis, thirty - three; from Sardis to Philadelphia, twenty - seven; from Philadelphia to Laodicea, about forty - two miles.
Re 1:11 I am Alpha and Omega. These words are omitted in the Revised Version, as not found in the best MSS. What thou seest. In all the visions of the Book of Revelation. Write in a book. The Greek says "in a roll", which was the form of books in the East at that time. Unto Ephesus. The seven churches are now named. For notes on these churches and the cities where they were located, see chapters 2 and 3. Two of the churches named had received epistles from the Apostle Paul.
