The parashah Ki Tisa begins with the elevation of the Jewish people: "When you lift up the heads of the Children of Israel" is the literal translation of the second verse. However, it then recounts a descent of Israel: the sin of the Golden Calf. How can such a grave sin, the root of all sins, which caused a great spiritual fall for the Jewish people, be found within a parashah whose name is "Tisa"—isn't sin the opposite of elevation? The source of this question arises from the teaching of our sages, that the name of everything indicates its conceptual content. Therefore, the names of each parashah carry within them the conceptual content of the parashah. In our case, the parashah is called "Elevation," while the content is "Descent.".
Furthermore, several details in the parashah require explanation. Following the sin of the Golden Calf, the Torah describes the significance of the First Tablets of the Testimony: "They are the work of God, and the writing is the writing of God." Apparently, the appropriate place to describe the Tablets is in Parashat Mishpatim, where God commands Moses to ascend Mount Sinai to receive them, and not here as a continuation of the sin. Similarly, we must understand why Moses' face shone only when he descended with the Second Tablets and not also when he descended the mountain with the First Tablets of the Testimony.
To understand the answer to all these questions, we must first know that everything in the universe has three stages: beginning, development, and end. The beginning of everything is how it arises from God. Then, in its development, the thing becomes part of the definitions and limitations of creation, where a descent is possible, caused by creation itself. The end of everything is the final ascent—the return to its source, or, in other words, the ultimate fulfillment of its purpose and reason for being.
The parashah Ki Tisa contains within itself these three steps.
That is why it is called "Tisah"—elevation—because the Torah reveals the inner content of everything, and this is the ultimate elevation. Even the deepest descent, like that caused by the sin of the Golden Calf, is a necessary descent for a subsequent ascent, and it is the cause of that great ascent.
Our sages say "the only reason the People of Israel made the Golden Calf is to give an excuse to the baalei teshuva —those who return to the path of Torah." They also said, "The People of Israel were not worthy of such an act." The sin of the Golden Calf, which caused such a great decline, was ultimately transformed into a path to lead the Jewish People to a great ascent. teshuvah.
Therefore, the parashah emphasizes the importance of the First Tablets. Their high spiritual level symbolizes the first step of all things, how they arise from God. Then comes the second step, the descent caused by creation itself. It is only through this descent that one can reach the ultimate elevation of the Second Tablets.
God said to Moses, "Do not be saddened by the First Tablets, for they only contained the Ten Commandments. In the Second Tablets I will give you..." halakhot - laws, midrash - interpretations and Hagadoth "Stories... double the amount." They also said, "If the People of Israel had not sinned, they would have been given only the Five Books of Moses and the Book of Joshua." From this we see that sin itself brings a great outpouring of Torah that had not been given before (nor would it have been given afterward).
The great elevation that comes with the Second Tablets of the Testimony was also expressed in the fact that "Moses' face shone." Since Moses then received a revelation of superior wisdom (both Written and Oral Torah), his face shone, as it is written: "A person's wisdom illuminates their face." This ascent is a preparation for the final ascent that will come with the complete Redemption, soon to be realized in our day.
