Revelation 16:18
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Καὶ ἐγένοντο ἀστραπαὶ καὶ βρονταὶ καὶ φωναί, καὶ σεισμὸς μέγας, οἷος οὐκ ἐγένετο ἀφ’ οὗ οἱ ἄνθρωποι ἐγένοντο ἐπὶ τῆς γῆς, τηλικοῦτος σεισμός, οὕτως μέγας.
And there were flashes of lightning, rumblings, peals of thunder, and a great earthquake the likes of which had not occurred since men were upon the earth—so mighty was the great quake.
