Exodus 19:16
Rahlfs Septuagint (1935) · Berean Standard Bible
ἐγένετο δὲ τῇ ἡμέρᾳ τῇ τρίτῃ γενηθέντος πρὸς ὄρθρον καὶ ἐγίνοντο φωναὶ καὶ ἀστραπαὶ καὶ νεφέλη γνοφώδης ἐπ᾿ ὄρους Σινα φωνὴ τῆς σάλπιγγος ἤχει μέγα καὶ ἐπτοήθη πᾶς ὁ λαὸς ὁ ἐν τῇ παρεμβολῇ
On the third day, when morning came, there was thunder and lightning. A thick cloud was upon the mountain, and a very loud blast of the ram’s horn went out, so that all the people in the camp trembled.
