“Write the things which thou hast seene, and the things which are, and the things which shall be hereafter,”
1611 King James Version (KJV)
1:19 Write the things which thou hast seen - This day: which accordingly are written, #Rev 1:11 |- 18. And which are - The instructions relating to the present state of the seven churches. These are written, #Rev 1:20 |- Rev 3:22. And which shall be hereafter - To the end of the world; written, #Rev 4:1|, &c.
Re 1:19 Write the things which thou hast seen. Not only the vision just seen, but the things which are, viz., the description of the state of the churches given in chapters 2 and 3; and also the things which shall be hereafter, viz., the revelation of future history recorded in chaps. 6-20.
