Sometimes the basis of the Torah comes through its annulment[1]
ולא-קם נביא עוד בישראל כמשה אשר ידעו יקוק פנים אל פנים: לכל-האותות והמופתים אשר שלחו יקוק לעשות בארץ מצרים לפרעה ולכל-עבדיו וכל-ארצו: ולכל היד החזקה ולכל המורא הגדול אשר עשה משה לעיני כל ישראל
No prophet arose in Israel like Moshe, who knew Hashem face to face. [As shown by] all the signs and wonders that Hashem sent him to perform in Egypt to Pharaoh, all of his servants, and his entire land, [and all] the mighty hand, as well as all the great astonishments that Moshe performed before the eyes of all of Israel[2]
The conclusion of the Torah describes the uniqueness of the prophecy of Moshe, as well as all the amazing feats that he performed in his life. The last words, לעיני כל ישראל, before the eyes of all of Israel, are understood by Chazal[3] to be hinting to the breaking of the two tablets after the sin of the Golden Calf[4]. Upon witnessing the Jews worship the idol they had made, Moshe took the tablets which contained the Ten Commandments, which he had received directly from Hashem, and smashed them on the ground. The Jews witnessed this dramatic reaction of their leader, and immediately halted their idol worship. One would have expected the Torah to end on a more positive note[5]. The incident of the Golden Calf was one of the lowest points in the Jews’ history in the wilderness. Why did the Torah end with a hint to the breaking of the tablets?
