Deuteronomy 4:11
Swete's Septuagint · Berean Standard Bible
καὶ προσήλθετε καὶ ἔστητε ὑπὸ τὸ ὄρος· καὶ τὸ ὄρος ἐκαίετο πυρὶ ἕως τοῦ οὐρανοῦ, σκότος, γνόφος, θύελλα, φωνὴ μεγάλη.
You came near and stood at the base of the mountain, a mountain blazing with fire to the heavens, with black clouds and deep darkness.
