Hebrews 12:26
Patriarchal Greek New Testament (1904) · Berean Standard Bible
οὗ ἡ φωνὴ τὴν γῆν ἐσάλευσε τότε, νῦν δὲ ἐπήγγελται λέγων· ἔτι ἅπαξ ἐγὼ σείω οὐ μόνον τὴν γῆν, ἀλλὰ καὶ τὸν οὐρανόν.
At that time His voice shook the earth, but now He has promised, “Once more I will shake not only the earth, but heaven as well (note: Haggai 2:6).”
