It's Simply Revelation

Does the Old Testament of the Bible tell us about things that are in the Book of Revelation? Ecclesiastes 1: 9 The thing that hath been, it is that which shall be, and that which is done is that which shall be done: and there is no new thing under the sun. Ecclesiastes 3: 15 That which hath been is now, and that which is to be hath already been, and God requireth that which is past. Isaiah 45: 11 Thus saith the LORD, The Holy One of Israel, and his Maker, Ask me of things to come concerning my sons, and concerning the work of my hands command ye me. Isaiah 46: 10 Declaring the end from the beginning, and from ancient times the things that are not yet done, saying, My counsel shall stand, and I will do all my pleasure.
