Revelation 4:1
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Μετὰ ταῦτα εἶδον, καὶ ἰδού, θύρα ἀνεῳγμένη ἐν τῷ οὐρανῷ, καὶ ἡ φωνὴ ἡ πρώτη ἣν ἤκουσα ὡς σάλπιγγος λαλούσης μετ’ ἐμοῦ, λέγων, Ἀνάβα ὧδε, καὶ δείξω σοι ἃ δεῖ γενέσθαι μετὰ ταῦτα.
After this I looked and saw a door standing open in heaven. And the voice I had previously heard speak to me like a trumpet was saying, “Come up here, and I will show you what must happen after these things.”
