Midrash sa Deuteronomio 9:29: Mekhilta DeRabbi Yishmael, Midrash Tanchuma Buber, Midrash Tanchuma & Pesikta Rabbati

And whence do we find that he gave his life for Torah? In (Exodus 34:28) "And he was there with the L–rd (to receive the Torah) … Bread he did not eat, etc." And it is written (Devarim 9:10) "And I stayed on the mountain forty days and forty nights, etc." — Because he devoted his life to Torah, it was called by his name. Because he devoted his life to Israel, they were called by his name, viz. (Exodus 32:7) "Go, descend, for your people have wrought corruptly." Now are they not the people of the L–rd? viz. (Devarim 9:29) "For they are Your people and Your inheritance," and (Ezekiel 36:20) "… when it was said of them: These are the people of the L–rd, and they came out of His land." How, then, are we to understand "Go, descend, for your people have wrought corruptly"? Because he devoted his life to them, they were called by his name. And whence do we find that he devoted his life to them? In (Exodus 2:11) "And it was in those days that Moses grew, and he went out to his brothers and he saw their toils," and (bid. 12) "And he turned here and there (… and he smote the Egyptian, etc.") Because he devoted his life to them, they were called by his name.

(Job 22:28:) WHEN YOU DECREE SOMETHING, IT SHALL COME TO PASS FOR YOU. The Holy One has spoken to the righteous (tsaddiq) one: If you have done my will, I also will put your will ahead of my own. (Ibid.:) WHEN YOU DECREE SOMETHING, IT SHALL COME TO PASS FOR YOU…. R. Berekhyah the Priest said: What is the meaning of IT SHALL COME TO PASS FOR YOU? The Holy One has said to the righteous one: When I say something and you say something < else >, I abrogate mine, as it were, to make yours come to pass. Ergo: IT SHALL COME TO PASS FOR YOU. When was the pronouncement? When < Israel > committed that act (i.e., of the golden calf). What did the Holy One do? He said to Moses (in Exod. 32:7): GO AND GET DOWN, FOR YOUR PEOPLE < WHOM YOU BROUGHT UP FROM THE LAND OF EGYPT > HAVE ACTED BASELY. What is written (in vs. 10)? SO NOW LEAVE ME ALONE < SO THAT MY ANGER MAY BURN AGAINST THEM >…. Moses immediately rose up in prayer and supplication, as stated (in vs. 11): BUT MOSES IMPLORED < THE LORD HIS GOD >…. (Deut. 9:26, 29:) O LORD GOD, DO NOT DESTROY YOUR PEOPLE AND YOUR HERITAGE…. FOR THEY ARE YOUR PEOPLE AND YOUR HERITAGE…. The Holy One said to him: I cannot < endure them >. He said to him: Just as you have endured them from Egypt up to now, so endure them < this time >. (Numb. 14:19-20:) PLEASE PARDON THE INIQUITY OF THIS PEOPLE < ACCORDING TO YOUR GREAT STEADFAST LOVE, EVEN AS YOU HAVE PARDONED THIS PEOPLE FROM EGYPT UP TO NOW >. THEN THE LORD SAID: I HAVE PARDONED THEM AS YOU ASKED. Immediately (according to Exod. 32:14): THE LORD REPENTED OF THE EVIL WHICH HE HAD PLANNED TO DO TO HIS PEOPLE. (Job 22:28:) WHEN YOU DECREE SOMETHING, IT SHALL COME TO PASS FOR YOU. Jacob also vowed things before the Holy One. Where is it shown? Where it is stated (in Gen. 28:20-21): THEN JACOB VOWED A VOW, SAYING: < IF GOD IS WITH ME, PROTECTS ME ON THIS WAY THAT I GO, AND GIVES ME FOOD TO EAT AND CLOTHING TO PUT ON >, AND IF I RETURN SAFELY UNTO MY FATHER'S HOUSE, < THE LORD SHALL BE MY GOD >. He said to him: My father, Isaac, wanted to go abroad, but you did not permit him because he was a whole burnt offering. You appeared to him and said to him (in Gen. 26:2): DO NOT GO DOWN TO EGYPT. Now I am going away, not for my benefit, but < from > before my brother lest he kill me. I have received permission from you and from my father. Do not forsake me. (Gen. 28:20:) THEN JACOB VOWED A VOW, < SAYING >:

Four are called "inheritance": the Temple — viz. "in the mountain of Your inheritance." Eretz Yisrael — viz. (Devarim 15:4) "in the land which the L–rd Your G–d gives You as an inheritance." Torah — viz. (Numbers 21:19) "And from Matanah ('the gift' [of Torah]) Nachaliel ('the inheritance of the L–rd'"). Israel — viz. (Yoel 4:2) "My people and My inheritance, Israel." The Holy One Blessed be He said: Let Israel, who are called "inheritance," come to Eretz Yisrael, which is called "inheritance," and build the Temple, which is called "inheritance," in the merit of Torah, which is called "inheritance."
