(10) Why did [Moses] see fit to say “Hear O Israel” at this point? The Rabbis say, “To what can this be compared? To a king who betroths a noblewoman with two pearls. She loses one of them. The king says to her, ‘You lost one, I will guard the other!’ So did the Holy One, blessed be He, betroth Israel with ‘Naaseh v’Nishma’ - ‘We will do and we will hear.’ They lost the ‘Naaseh’ at the Golden Calf. Moses said to them: You lost the Naaseh, guard the Nishma!

(12) "Thereupon the LORD said to me, 'Carve out etc.'" (Deut. 10:1). A halachic question: When a Jewish man betrothes a woman, who must provide the payment for the scribing of the marriage document? Our Sages taught as follows: Betrothal and marriage documents are written only with the assent of both parties, and the groom provides the payment. From whom do we learn this? From the Holy One Blessed be He, when He betrothed Israel on Sinai, as it is written (Ex. 19:10), "Adonai said to Moses, “Go to the people and warn them to stay pure today and tomorrow." And who wrote this document? Moshe. Whence? As it says (Deut. 31:9), "Moses wrote down this (Song) Teaching." And what payment did the Holy One Blessed be He provide for him? The splendor of his face, as it is written (Ex. 34:29), "Moses was not aware that the skin of his face was radiant" -- when? "when He spoke with him." Resh Lakish said, "At the time he wrote the Torah, Moshe acquired the splendor of his face." How? Resh Lakish said,"The Torah was given to Moshe, its skin of white fire and written with black fire, and sealed in fire, and wrapped with fire. And while he was writing, he wiped his pen-reed on his hair, and from there he acquired the splendor of his face." R' Shmuel bar Nahman said, "It was from the tablets that Moshe acquired the splendor of his face. While the tablets were being given to him from hand to hand, Moshe acquired the splendor of his face. As soon as Israel did That Deed, he took them and broke them. The Holy One Blessed be He said to him, 'When you made the arrangement with Israel, I gave you your payment, the splendor of your face. and now you have broken the tablets.'" R' Yitzhak said, "Our Sages learned, 'If the barrel breaks, it breaks [to the account of] the middleman.' The Holy One Blessed by He said to him, 'You were the middleman between Me and My children. You broke; you replace. Whence? Because so it is written (Ex. 34:1-3): "The LORD said to Moses: 'Carve two tablets of stone like the first, and I will inscribe upon the tablets the words that were on the first tablets, which you shattered. Be ready by morning, and in the morning come up to Mount Sinai and present yourself there to Me, on the top of the mountain. No one else shall come up with you, and no one else shall be seen anywhere on the mountain; neither shall the flocks and the herds graze at the foot of this mountain.”
