Exodus 34:29

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 it came to pass, when Moses came down from mount Sinai with the two tables of testimony in Moses’ hand, when he came down from the mount, that Moses wist not that the skin of his face shone while he talked with him.

When Moses came down from Mount Sinai with the two tablets of the covenant in Moses’ hand, when he came down from the mountain, Moses didn’t know that the skin of his face shone by reason of his speaking with him.
