Revelation 4:1
Patriarchal Greek New Testament (1904) · Berean Standard Bible
Μετὰ ταῦτα εἶδον, καὶ ἰδοὺ 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.”
