Strange as it may seem that Israel should set out to worship this idol at the very time when God was busied with the preparation of the two tables of the law, still the following circumstances are to be considered. When Moses departed from the people to hasten to God to receive the Torah, he said to them: "Forty days from to-day I will bring you the Torah." But at noon on the fortieth day Satan came, and with a wizard's trick conjured up for the people a vision of Moses lying stretched out dead on a bier that floated midway between earth and heaven.
Pointing to it with their fingers, they cried: "This is the man Moses that bought us up out of the land of Egypt." Under the leadership of the magicians Jannes and Jambres, they appeared before Aaron, saying: "The Egyptians were wont to carry their gods about with them, to dance and play before them, that each might be able to behold his gods; and now we desire that thou shouldst make us a god such as the Egyptians had."
When Hur, the son of Miriam, whom Moses during his absence had appointed joint leader of the people with Aaron, owing to his birth which placed him among the notables of highest rank, beheld this, he said to them: "O ye frivolous ones, you are no longer mindful of the many miracles God wrought for you." In their wrath, the people slew this pious and noble man; and, pointing out his dead body to Aaron, they said to him threateningly: "If thou wilt make us a god, it is well, if not we will dispose of thee as of him."
Aaron had no fear for his life, but he thought: "If Israel were to commit so terrible a sin as to slay their priest and prophet, God would never forgive them." He was willing rather to take a sin upon himself than to cast the burden of so wicked a deed upon the people. He therefore granted them their wish to make them a god, but he did it in such a way that he still cherished the hope that this thing might not come to pass.
Hence he demanded from them not their own ornaments for the fashioning of the idol, but the ornaments of their wives, their sons, and their daughters, thinking: "If I were to tell them to bring me gold and silver, they would immediately do so, hence I will demand the earrings of their wives, their sons, and their daughters, that through their refusal to give up their ornaments, the matter might come to nought."
But Aaron's assumption was only in part true; the women indeed did firmly refuse to give up their jewels for the making of a monster that is of no assistance to his worshippers. As a reward for this, God gave the new moons as holidays to women, and in the future world too they will be rewarded for their firm faith in God, in that, like the new moons, they too, may monthly be rejuvenated. But when the men saw that no gold or silver for the idol was forthcoming from the women, they drew off their own earrings that they wore in Arab fashion, and brought these to Aaron.
