Exodus 19:18
Rahlfs Septuagint (1935) · Berean Standard Bible
τὸ δὲ ὄρος τὸ Σινα ἐκαπνίζετο ὅλον διὰ τὸ καταβεβηκέναι ἐπ᾿ αὐτὸ τὸν θεὸν ἐν πυρί καὶ ἀνέβαινεν ὁ καπνὸς ὡς καπνὸς καμίνου καὶ ἐξέστη πᾶς ὁ λαὸς σφόδρα
Mount Sinai was completely enveloped in smoke, because the LORD had descended on it in fire. And the smoke rose like the smoke of a furnace, and the whole mountain quaked violently.
