“And he that sat upon the throne said, Behold, I make all things new. And he said unto me, Write: for these words are true and faithful.”
King James Version (KJV)
21:5 And he that sat upon the throne said - Not to St. John only. From the first mention of him that sat upon the throne, #Rev 4:2|, this is the first speech which is expressly ascribed to him. And he - The angel. Saith to me Write - As follows. These sayings are faithful and true - This includes all that went before. The apostle seems again to have ceased writing, being overcome with ecstasy at the voice of him that spake.
Re 21:5 Behold, I make all things new. See PNT "Re 21:1". Write. This is the third time in this book, in addition to the epistles to the churches (Re 2:1,8,12,18 3:1,7,14), where John receives the special command to "write". The other examples are in Re 14:13 19:9. See also Re 1:11,19.
