Revelation 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.
