Then I turned to see the voice that spoke with me. And having turned I saw seven golden lampstands, and in the midst of the seven lampstands One like the Son of Man, clothed with a garment down to the feet and girded about the chest with a golden band. His head and hair were white like wool, as white as snow, and His eyes like a flame of fire; His feet were like fine brass, as if refined in a furnace, and His voice as the sound of many waters; He had in His right hand seven stars, out of His mouth went a sharp two-edged sword, and His countenance was like the sun shining in its strength. And when I saw Him, I fell at His feet as dead. But He laid His right hand on me, saying to me, “?Do not be afraid; I am the First and the Last. I am He who lives, and was dead, and behold, I am alive forevermore. Amen. And I have the keys of Hades and of Death.
Christ claims to be the first and the last.
