Midrash sa Exodo 2:11: Mekhilta DeRabbi Yishmael, Shemot Rabbah, Midrash Tanchuma & Kohelet Rabbah

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.

“It was in those days, Moses grew and went out to his brethren, and he saw their burdens; he saw an Egyptian man beating a Hebrew man of his brethren” (Exodus 2:11).
“It was in those days, Moses grew,” – Moses was twenty years old at that time, and some say forty years old. “Moses grew.” Doesn’t everyone grow? Rather, it is telling you that he grew in an atypical manner. “And went out to his brethren,” this righteous one went out twice⁶¹Moses left the palace twice to check on his brethren. and the Holy One blessed be He wrote them one after another; “he went out on the second day” (Exodus 2:13), these are two.
“He saw their burdens.” What is “he saw”? He would see their burdens and cry and say: ‘Woe is me over you; would that I could die for you. There is no labor more arduous than labor with mortar.’ He would shoulder [the burdens] and help each and every one of them. Rabbi Elazar son of Rabbi Yosei HaGelili says: He saw a large burden on a small man and a small burden on a large man; the burden of a man on a woman and the burden of a woman on a man; the burden of an elderly man on a lad and the burden of a lad on an elderly man. He would leave his royal guard and would arrange their burdens, feigning as though he was helping Pharaoh. The Holy One blessed be He said: ‘You left your affairs and went to observe the Israelite’s suffering, and you treated them in a brotherly manner; I will leave the upper and lower worlds to speak with you.’ That is what is written: “The Lord saw that he had turned to see” (Exodus 3:4); the Holy One blessed be He saw that he turned from his affairs to see their burdens; therefore, “God called to him from the midst of the bush” (ibid.).

“He settled in the land of Midyan, and sat alongside the well.” He learned the way of the patriarchs. Three were paired with their mates at the well; Isaac, Jacob, and Moses. Regarding Isaac, it is written: “Isaac came from going to Be’er [laḥai ro’i]” (Genesis 24:62).⁶⁶This is the well where God had once appeared to Hagar. This is the context in which Isaac met Rebecca, who was returning with Abraham’s servant, identified by the midrash as Eliezer. Isaac then married her; see Genesis 24:63-67. Moreover, Rebecca met Eliezer near the spring. Jacob, “he saw, and behold, there was a well in the field” (Genesis 29:2); ⁶⁷It was there that Jacob first met Rachel; see Genesis 29:10-11. Moses, “and he sat alongside the well.”
“The priest of Midian had seven daughters; they came and they drew water and filled the troughs to give their father’s flock to drink” (Exodus 2:16).
“The priest of Midian had seven daughters.” But doesn’t the Holy One blessed be He hate idol worship, and yet He provided Moses haven with an idol worshipper? Rather, our Rabbis said: Yitro was a priest for idol worship and he saw that it lacked substance, and he scorned it, and he thought about repenting before Moses arrived. He called the residents of his city and said: ‘Until now, I have served you. Now I am old; choose another priest.’ He arose and removed the service vessels of idol worship and gave them all to them. They arose and ostracized him so that no one should have ties with him, no one should perform labor for him, and no one should herd his flocks. He asked the shepherds to herd his flocks for him, but they did not agree; therefore, he sent his daughters out.
“They came and they drew.” It teaches that they would arrive early due to fear of the shepherds.
“The shepherds came and drove them away; Moses rose and rescued them and gave their flocks to drink” (Genesis 2:17).
“The shepherds came and drove them away.” Is it possible that he was the priest of Midyan and the shepherds were driving away his daughters? Rather, it teaches you that they ostracized him and drove away his daughters like a divorced woman, like you say: “He drove out the man” (Genesis 3:24).⁶⁸In this verse, God permanently banished man from the Garden of Eden. So too, the shepherds sought to permanently banish Yitro’s daughters.
“Moses rose and rescued them.” This teaches that he sat in judgment regarding them.⁶⁹This is derived from the fact that the verse says that he rose, indicating that beforehand he was sitting. He said: Typically, men draw the water and women give the flocks to drink, while here, women draw and men give the flocks to drink. It does not say “he saved them [vayatzilan],” but rather, “he rescued them [vayoshian].” Rabbi Yoḥanan says in the name of Rabbi Eliezer son of Rabbi Yosei HaGelili: They came to engage with them in a matter of forbidden sexual relations; here it is stated: “Moses rose and rescued them ,” and there it is stated: “The betrothed young woman screamed, and there was no one to rescue her” (Deuteronomy 22:27). Just as there, it is referring to forbidden sexual relations, here too it is referring to forbidden sexual relations.
The Rabbis say: This teaches that they cast them into the water and Moses saved them. Vayoshian is nothing other than an expression of saving from water, as it is stated: “Rescue me God, as the water has reached my soul” (Psalms 69:2). “And gave their flocks to drink.” This teaches that Moses drew water for them and gave their flocks to drink, just as Jacob did for Rachel.
“They came to their father Reuel. He said: Why were you quick to come today?” (Exodus 2:18).
“They came to their father Reuel.” This is Yitro. Why is he named Reuel? It is because he became a companion to God. “He said: Why were you quick to come today?” From here you learn that on all days they would come last.
“They said: An Egyptian man saved us from the shepherds and also drew water for us and gave the flock to drink” (Exodus 2:19).
“They said: An Egyptian man saved us from the shepherds.” Was Moses an Egyptian? Rather, his garb was Egyptian, but he was a Hebrew. Alternatively, “an Egyptian man,” this is analogous to one who was bitten by a deadly snake and was running to put his legs in water. He placed them in the river and saw a certain child sinking in the water, and he extended his hand and saved him. The child said to him: ‘Were it not for you, I would have died.’ He said to him: ‘It is not I who saved you, but rather, the deadly snake that bit me and I fled from it; it saved you.’ Similarly, Yitro’s daughters said to Moses: ‘Well done that you saved us from the shepherds.’ Moses said to them: ‘That Egyptian whom I killed, he saved you.’ That is why they said to their father, “an Egyptian man saved us,” in other words: Who caused this one to come to us? It is the Egyptian man whom he killed.
“Drew water [dalo dala],” he drew one drawing of water and gave water to all the flocks to drink, and the water was blessed for his sake. That is what is written: “and gave the flock to drink.” Our flock is not written, but rather “the flock,” as he gave even the flocks of the shepherds to drink. What then is “for us”? It means that he drew us out, too, as the shepherds cast us into the water and he took us out.
“He said to his daughters: Where is he? Why did you leave the man? Call him so that he will eat bread” (Exodus 2:20).
“He said to his daughters: Where is he?” He said to them: ‘The fact that you say that he drew water and gave water to all the flocks is an indicator that he is one of the descendants of Jacob who stood at the well and the water was blessed for his sake.’
“Why did you leave the man? [Call him so that he will eat bread],” – perhaps he will marry one of you. The eating of bread mentioned here refers to nothing other than a wife, similar to: “Except for the bread that he eats” (Genesis 39:6).⁷⁰Joseph stated this in reference to Potifar’s wife. Immediately, Tzipora ran after him like a bird [tzipor] and brought him. Why was she named Tzipora? It is because she purified the house like a bird.⁷¹The bird plays a central role in the purification process of a leprous house; see Leviticus 14:48-53
