(1) When the people saw that Moses was so long (כִּֽי־בֹשֵׁשׁ מֹשֶׁה) in coming down from the mountain, the people gathered against Aaron and said to him, “Come, make us a god who shall go before us, for that man Moses, who brought us from the land of Egypt—we do not know what has happened to him.” (2) Aaron said to them, “Take off the gold rings that are on the ears of your wives, your sons, and your daughters, and bring them to me.” (3) And all the people took off the gold rings that were in their ears and brought them to Aaron. (4) This he took from them and cast in a mold, and made it into a molten calf. And they exclaimed, “This is your god, O Israel, who brought you out of the land of Egypt!” (5) When Aaron saw this, he built an altar before it; and Aaron announced: “Tomorrow shall be a festival of Adonai!” (6) Early next day, the people offered up burnt offerings and brought sacrifices of well-being; they sat down to eat and drink, and then rose to dance.
That Moses was so long in coming down: The verb used here (בֹשֵׁשׁ, boshes) ordinarily means "to be ashamed." When Moses went up the mountain he had told them, "I will be back after 40 days, before noon." They thought that the day he went up the mountain was the first of the 40, but he actually meant 40 full days, including both night and day. The day he went up the mountain did not, of course, include the pervious night, when the day actually began. Since he went up the mountain on the 7th of Sivan, the 40th day works out to be the 17th of Tammuz. On the 16th ... [the Israelites said among themselves] "Moses must be dead, for ba shesh, the 6th hour has come-- it is past noon and he is not back."
He built an altar. As a ploy to put them off.
"Tomorrow shall be a festival of Adonai!": "He said, "tomorrow" rather than "today," assuming that Moses would show up before they actually worshipped it.
(15) Thereupon Moses turned and went down from the mountain bearing the two tablets of the Pact, tablets inscribed on both their surfaces: they were inscribed on the one side and on the other. (16) The tablets were God’s work, and the writing was God’s writing, incised upon the tablets. (17) When Joshua heard the sound of the people in its boisterousness, he said to Moses, “There is a cry of war in the camp.” (18) But he answered, “It is not the sound of the tune of triumph, Or the sound of the tune of defeat; It is the sound of song that I hear!” (19) As soon as Moses came near the camp and saw the calf and the dancing, he became enraged; and he hurled the tablets from his hands and shattered them at the foot of the mountain.
When they saw that Moses delayed (from coming down the mountain) they lost their faith, and sought out a foreign god to use as a conduit for god... and this is why Moses was enraged: "Do you think that I am important? What holiness is there other than God? To the extent that in my absence you make a calf! Heaven forbid, I am a person just like you, and the Torah does not rely on me, and even if I were not to have come, the Torah would not change.
Moses did not prevent himself from breaking the tablets for he was enraged upon seeing this evil spectacle, and he could not bear it.
What did Moses do? He took the tablets from the hand of the Holy Blessed One in order to calm God's anger...When the Jewish people sinned, Moses took the tabletsmand broke them, so as to say that if they would have seen their punishment, they would have not sinned.
When Moses took the tablets and went down (the mountain), and the letters were carrying themselves [as well as] Moses... and when the (letters) saw the instruments and the golden calf, they flew off the tablets, and became heavy. Moses could no longer carry them, so he threw them out of his hands, as it says, "and he broke them under the mountain.”
