Not on the throne, but perhaps in the space in the center of which is the throne, and which is surrounded by the twenty-four elders.
A Lamb (ἀρνίον)
The diminutive, very frequent in Revelation, and once in the Gospel of John (Joh 21:15). Nowhere else in the New Testament. Compare Isa 53:7; Joh 1:29, Joh 1:36. Christ had just been spoken of as a lion. He now appears as a lamb. Some interpreters emphasize the idea of gentleness, others that of sacrifice.
Slain (ἐσφαγμένον)
The verb indicates violence, butchery. See on 1Jo 3:12. It is also the sacrificial word. Exo 12:6.
Stood (ἑστηκὸς)
Rev., more correctly, standing. Though slaughtered the lamb stands. Christ, though slain, is risen and living.
Seven horns and seven eyes
See remarks on the Apocalyptic imagery, Rev 1:16. The horn is the emblem of might. See 1Sa 2:10; 1Ki 22:11; Psa 112:9; Dan 7:7, Dan 7:20 sqq.; Luk 1:69. Compare Mat 28:18. The eyes represent the discerning Spirit of God in its operation upon all created things.
