His eyes are a fiery flame, and upon his head are many diadems.”​—Revelation 19:11, 12a.

His eyes are fear inspiring, like “a fiery flame,” looking to the coming fiery destruction of his foes.

⁶ Diadems crown the head of this Warrior-King. The wild beast that John saw coming out of the sea had ten diadems, picturing its temporary rulership of the earthly scene. (Revelation 13:1) Jesus, though, has “many diadems.” His glorious rulership is unmatched, since he is “King of those who rule as kings and Lord of those who rule as lords.”​—1 Timothy 6:15.

7. What is the written name that Jesus has?

⁷ John’s description continues: “He has a name written that no one knows but he himself.” (Revelation 19:12b) The Bible already speaks of God’s Son by names such as Jesus, Immanuel, and Michael. But this unstated “name” appears to stand for the position and privileges that Jesus enjoys during the Lord’s day. (Compare Revelation 2:17.) Isaiah, describing Jesus since 1914, says: “His name will be called Wonderful Counselor, Mighty God, Eternal Father, Prince of Peace.” (Isaiah 9:6) The apostle Paul associated Jesus’ name with His very high privileges of service when he wrote: “God exalted [Jesus] to a superior position and kindly gave him the name that is above every other name, so that in the name of Jesus every knee should bend.”​—Philippians 2:9, 10.

8. Why is it that only Jesus can know the name written, and with whom does he share some of his lofty privileges?

⁸ Jesus’ privileges are unique. Apart from Jehovah himself, only Jesus can comprehend what it means to hold such a high position. (Compare Matthew 11:27.) Therefore, of all God’s creatures, only Jesus can fully appreciate this name. Nevertheless, Jesus does include his bride in some of these privileges. So he makes this promise: “The one that conquers . . . I will write upon him . . . that new name of mine.”​—Revelation 3:12.
