Then I saw a Lamb who appeared to have been slain, standing in the center of the throne, encircled by the four living creatures and the elders. The Lamb had seven horns and seven eyes, which represent the seven Spirits of God sent out into all the earth.
Textus Receptus (TR) - Revelation 5:6 >Καὶ εἶδον, καὶ ἰδού, ἐν μέσῳ τοῦ θρόνου καὶ τῶν τεσσάρων ζῴων, καὶ ἐν μέσῳ τῶν πρεσβυτέρων, ἀρνίον ἑστηκὸς ὡς ἐσφαγμένον, ἔχον κέρατα ἑπτὰ καὶ ὀφθαλμοὺς ἑπτά, οἵ εἰσι τὰ ἑπτὰ τοῦ Θεοῦ πνεύματα τὰ ἀπεσταλμένα εἰς πᾶσαν τὴν γῆν.
