Rashi notes that the words “k’chaloso,” when he finished, is spelled defectively, without the letter “vov” between the “lamed” and the “saf,” as if it were vocalized “k’kalaso,” which means like his bride. This implies that the Torah was given to Moshe as a gift, as a bride to a groom. Moshe was not able to grasp the entire Torah in such a short time. Indeed, as the Midrash comments, throughout the forty days that Moshe Rabbeinu was on Har Sinai, Hashem taught him the Torah, but he constantly forgot what he had learned. Moshe turned to Hashem and said, “Ribono Shel Olam, I have been here for forty days and I know nothing.” Finally, Hashem presented it to Moshe as a gift, as if it were his bride. We have to endeavor to understand why Hashem waited forty days before he gave Moshe the Torah as a gift? This gift could have been presented earlier.
Horav Zaidel Epstein, Shlita, explains that in order to receive the Torah one must be prepared for it. He must refine himself spiritually, raising his level of sanctity, purifying himself for the Torah. Moshe had to wait forty days in an environment of consummate holiness to prepare himself for the moment when he could accept the Torah on behalf of Klal Yisrael. It also goes without saying that Moshe’s ascendancy to the appropriate level of holiness was a daily endeavor. Every twenty-four hours the “Moshe” from the previous day was no longer. He was transformed and elevated to a higher spiritual plateau. On the fortieth day, Moshe achieved a level of holiness and purity never before imagined. Yet, this was not sufficient. He still forgot the Torah. He was not able to contain within himself the Torah on his own. On the fortieth day, however, he reached the point that he was now sufficiently prepared to receive the Torah as a gift. Torah is distant, completely removed from anything material or physical. Hence, in order for a human being to receive the Torah as a gift, he must prepare himself for it spiritually. There is yet one question to be addressed: Why was it necessary for Moshe to assert to Hashem that he was accomplishing nothing towards the goal of receiving the Torah before Hashem responded by giving it to him as a gift? Why did Hashem not simply give it to him at the end of his forty-day preparation period?
We derive from here that, as long as one does not sense that he is missing something, he will not strive to overcome that deficit. It was not sufficient for Moshe to sense that Torah was needed. He had to prepare himself to receive it. His preparation was still not enough to warrant his receiving the Torah as a gift until he asked for it. Only when we realize that without Torah our lives have no meaning and we expend effort to receive it, will we be ready to receive it as a Divine gift.
