Komentaryong Sumisipi para sa Exodo 34:29

And the boldness of his face is changed. From that of other people, to the extent that they feared “to approach him” [Moshe], “because the skin of his face was radiant.”²Shemos 34:29, 30. ³Alternatively, wisdom begets humility and does away with anger and arrogance (Ibn Ezra). Or, because of his wisdom, everyone admires and obeys him, giving him a jubilant countenance. (Metsudas Dovid)

rays The expression of a light, which, when piercing and shining through a hole, appears like protruding horns. Similarly, (Ex. 34:29) “For the skin of his face shone.”

ואפן וארד מן ההר, “I turned around and descended from the Mountain;” on the same day, on Tuesday, the tenth day of Tishrey. This is what is written in Exodus 34,29: ויהי ברדת משה מן ההר, “it happened while Moses was on his descent from the Mountain, etc.;” even though Moses had delayed briefly on the Mountain, he descended on that day and brought the second set of Tablets with him. This day is not included in the third 40 days that Moses had spent on the Mountain. Those forty days had already been completed at dawn of the day that Moses descended. Moses’ absences from the people, and his fasting, therefore commenced on Monday, the first day of Sivan, prior to the revelation on the sixth day of the month, as he had to completely discharge any remnants of food and drink consumed before he ascended the Mountain where he had to be comparable to angels who do not eat or drink. He therefore could remain in a constant state of ritual purity. He completed his fasting on Monday the ninth day of Tishrey. This is why it became a custom among some of our people to observe Mondays and Thursdays commencing with the first day of Sivan and concluding on the tenth day of Tishrey.

ונתתה מהודך עליו AND THOU SHALT PUT SOME OF THY GLORY UPON HIM — This refers to the shining of the skin of his countenance (see Exodus 34:29—30).
