Or HaChaim on Exodus 32:15/אור החיים על שמות ל״ב:ט״ו

1 ויפן וירד משה מן ההר, "Moses turned around and descended from the Mountain." What is the significance of the Torah reporting Moses as "turning around," i.e. turning His back on G'd's presence? Is this not something which reflects a lack of respect? Perhaps the fact that the Torah added the superfluous words "from the Mountain" were added to prevent the misconception that Moses "turned his back on G'd", as it were. He only turned his back on the Mountain. If that were the meaning of the words "from the Mountain," the Torah should have written "Moses turned away from the Mountain" instead of writing "Moses turned and descended from the Mountain." Furthermore, why did the Torah have to mention Moses as "turning around" altogether?

2Perhaps the expression "he turned around" signified Moses' reduced spiritual niveau which made it impossible for him to confront the angels. He therefore moved sideways on the Mountain, much like someone who tries to hide.

3We may also understand the word as similar to what we learned in Devarim Rabbah 1, where the Midrash contrasts Moses' mode of speaking directly to the Israelites, i.e. "you have sinned," with his speaking to G'd in the third person "למה יחרה?" The meaning of ויפן, he turned around, then may refer to Moses' change in attitude as he prepared to face his people.

4לוחות העדות, "the Tablets containing the testimony." The word ה־עדות, indicating a unique kind of testimony may be an allusion to the way G'd Himself had inscribed the Tablets so that the writing could be read from either side, something impossible if they had been inscribed by human hands. Such writing would appear as if it had been written backwards had it been inscribed on one side by a human scribe. The letter ה before the word עדות may also hint at the miraculous way the final letters ס and ם appeared with their respective centers suspended in the air miraculously (Megillah 3). Perhaps these two letters were "proof" i.e. "testimony" that the Tablets had indeed been inscribed by G'd Himself.
