And the people assembled themselves together around Aaron, and said to him: "Get up, make us gods." (Ex. 32:1)
Why did they ask this of Aaron instead of just appointing him in Moses' stead? The answer is that Aaron, "the pursuer of peace," was too close to the people for them to consider him as their leader. Too much familiarity makes it impossible for people to feel the proper respect for their leaders. (Rabbi Yitzchak of Vorka)
You shall see My back, but My face shall not be seen (Ex. 33:23)
According to Rashi's commentary, G-d showed Moses the "knot of the tefilin (phylacteries)." What are we to learn from this? Tefilin consist of two parts - one placed on the hand, and the other on the head. The hand represents interpersonal relationships, for it is with our hands that we extend aid and assistance to others, whereas the head, the seat of our intellect, is the medium through which we connect ourselves to G-d by learning His Torah. In order to serve G-d properly, the Jew must excel in both areas. Moses asked to see G-d's glory so that he would have a better understanding of what is required of the Jewish people. The knot of the tefilin symbolizes G-d's desire that every Jew bind these two aspects of our worship together - doing our utmost for our fellow Jews and at the same time devoting ourselves to Torah study. (Our Sages)
And he saw the calf and the dancing, and the anger of Moses waxed hot, and he threw the tablets from his hands (Exodus 32:19)
This underscores the difference between hearing about something and actually seeing it for oneself. Although G-d had already informed Moses of the Jews' transgressions, his reaction was more extreme once he had seen their behavior for himself.
When you shall take the sum (literally, "the head") of the Children of Israel... then shall they give every man a ransom for his soul (Ex. 30:12)
When the time will come for you to appoint a "head" - a leader of the Jewish people - make sure it is one who is willing to give up his very soul on behalf of his brethren; only one such as this is worthy. (Alshich)
