Exodus 34:29
Brenton's English Septuagint · Berean Standard Bible
And when Moses went down from the mountain, [there were] the two tables in the hands of Moses,—as then he went down from the mountain, Moses knew not that the appearance of the skin of his face was glorified, when God spoke to him.
And when Moses came down from Mount Sinai with the two tablets of the Testimony in his hands, he was unaware that his face had become radiant from speaking with the LORD.
