פָּרָשַׁת כִּי תִשָּׂא

(17) Thereupon I gripped the two tablets/Luchos and flung them away with both my hands, smashing them before your eyes.

(12) and for all the great might and awesome power that Moshe displayed before the eyes of all of Yisrael.

(1(3) לעיני כל ישראל-This refers to the fact that his heart inspired him to shatter the Tablets before their eyes, as it is said, (Devarim 9:17) “And I broke them before your eyes” (Sifrei Devarim 357:45), and the opinion of Hakadosh Baruch Hu, regarding this action agreed with his opinion, as it is stated that Hashem said of the Luchos, (Exodus 34:1) אשר שברת "Which you have broken", [which implies] "May your strength be fitting (יישר; an expression of thanks and congratulation) because you have broken them" (Yevamot 62a; Shabbat 87a).

Another explanation of פסל לך is: you broke the first ones. You should hew others for yourself. This can be compared to a king who went abroad and left his betrothed with the maidservants. Because of the immoral behaviour of the maidservants, she acquired a bad reputation. Her bridesman/guardian [the person appointed to defend the bride should any problems arise] arose and tore up her marriage contract. He said, “If the king decides to kill her, I will say to him, ‘She is not yet your wife.’” The king investigated and discovered that only the maidservants were guilty of immoral behavior. He [therefore] became appeased to her. So her bridesman said to him, “Write her another marriage contract because the first one was torn up.” The king replied to him, “You tore it up. You buy yourself another [sheet of] paper, and I will write to her with my [personal] hand [writing].” Likewise, the king represents Hakadosh Baruch Hu. The maidservants represent the Eiruv Rav. The bridesman/guardian is Moshe, and the betrothed of the Hakadosh Baruch Hu, is Israel. That is why it says: “Hew for yourself.” -[from Tanchuma 30]

...Two things preceded G‑d’s creation of the world: Torah and Israel. Still, I do not know which preceded which. But when Torah states `Speak to the Children of Israel…,’ `Command the Children of Israel…,’ etc., I know that Israel preceded all...
