Midrash sur L’Exode 18:4

“Your neck is like an ivory tower; your eyes are pools in Ḥeshbon, by the gate of Bat Rabim; your nose is like the tower of Lebanon overlooking Damascus” (Song of Songs 7:5).
“Your neck is like an ivory tower.” It is written: “Esau ran to meet him, embraced him, fell upon his neck, and kissed him [vayishakehu] [and they wept]” (Genesis 33:4). The entire word³²The word vayishakehu is written in the Torah scroll with a dot over each of the letters. is dotted. Rabbi Shimon ben Elazar said: Everywhere that you find the script more numerous than the dots, adopt the script and ignore the dots. If the dots are more numerous than the script, adopt the dots and ignore the script. However, here, neither is the script more numerous than the dots, nor are the dots more numerous than the script, but rather it is dotted above vayishakehu in its entirety. This teaches that he did not come to kiss him, but rather to bite him. Jacob’s neck became as hard as marble and the teeth of that wicked one became dull and melted like wax. Why does the verse state: “And they wept”? This one was crying over his neck, and that one was crying over his teeth.
Rabbi Abahu in the name of Rabbi Elazar cites it from this: “Your neck is like an ivory tower.” It is written: “Pharaoh heard this matter and he sought to kill Moses. Moses fled” (Exodus 2:15). Is there a person who is able to flee from the king? Rather, it teaches that he was standing and was sentenced on that same day, and they condemned him to beheading. Rabbi Evyatar said: The sword glanced off the neck of Moses and sliced the neck of the wicked executioner. That is what is written: “For the God of my father was my help, and He delivered me from the sword of Pharaoh” (Exodus 18:4). He delivered me, but did not deliver the executioner. Rabbi Bon would apply to him the verse: “The righteous is extricated from trouble, and the wicked comes in his place” (Proverbs 11:8). Rabbi Berekhya said: “The wicked is ransom for the righteous” (Proverbs 21:18). Bar Kappara said: It teaches that an angel descended in the guise of Moses, and they apprehended the angel and left Moses, and he fled. Rabbi Abba son of Rav Pappi and Rabbi Yehoshua of Sikhnin [said] in the name of Rabbi Levi: At that moment all of Pharaoh’s advisors, some of them became mute, some of them deaf, some of them blind, and some of them disabled. They said to the mutes: Where is Moses? But they could not speak. To the blind, but they could not see. To the deaf, but they could not hear. To the disabled, but they could not walk, as it is stated: “The Lord said to him: Who gives a mouth to a person, or who renders one mute or deaf, or sighted or blind? Is it not I, the Lord?” (Exodus 4:11). Is it not I who did all these? “Now go and I will send you to Pharaoh” (Exodus 3:10).

(Numb. 19:2, cont:) “That they bring unto you [a red heifer without blemish].” R. Jose bar Hanina said, “The Holy One, blessed be He, said to Moses. ‘To you I am revealing the reason for the heifer, but to others it is an unquestioned statute.’”⁸⁸PRK 4:7; PR 14:13; Numb. R. 19:6. As Rav Huna said, “It is written (in Ps. 75:3), ‘For I will set a time, when I Myself will judge with equity.’ It is also written (in Zech. 14:6), ‘On that day there shall be no light of cold (yqrot) and frost.’⁸⁹See also Pes. 50a. Things that are hidden from you in this world are going to be clear to you in the world to come, as with the blind person who gains his sight. Thus it is stated (in Is. 42:16), ‘I will lead the blind by a road they do not know, [… these things I have done].’ ‘I will do’ is not stated here, but ‘I have done,’ in that I have already done them for R. Aqiva and his colleagues.” Another interpretation: Things that were not revealed to Moses were revealed to R. Aquiva and his colleagues (as found in Job 28:10), “his eye sees every precious thing.” R. Jose bar Hanina said, “It was implied (in Numb. 19:2) was that all heifers perish, but [Moses’] lasts forever.” R. Aha said in the name of R. Jose bar Hanina, “When Moses ascended into the firmament, he heard the voice of the Holy One, blessed be He, sitting and being occupied with the parashah of the [red heifer], and he was reciting a halakhah (i.e., a passage of oral Torah) in the name of its author (from Parah 1:1), ‘My son, Eliezer says, “The calf [whose neck is to be broken]⁹⁰See Deut. 21:3-4. is to be one year old, but the [red] heifer is to be two years old.”’⁹¹See Braude’s translation of PR, 14:13 p. 290, n. 91, which records a suggestion of Mordecai Margulies, who notes that R. Eliezer would have begun his instruction with this mishnah. Moses said, ‘Master of the world, do not the realms above and below belong to you? Now you are citing a halakhah in the name of flesh and blood?’ He said to him, ‘A righteous man is going to arise in my world and is first going to begin [his teaching] with the parashah of the [red] heifer, R. Eliezer says, “The calf [whose neck is to be broken] is to be one year old, but the [red] heifer is to be two years old.”’ He told Him, ‘Master of the universe, may it be [Your] will that he come from my loins.’ He said to him, ‘By your life, he is to be from your loins.’ Thus it is stated (of Moses' offspring in Exod. 18:4), ‘And the name of the one⁹²So literally. In the biblical context the translation would normally read: AND THE NAME OF THE OTHER WAS ELIEZER. was Eliezer,’ [i.e.,] the name of that particular one [who would begin his teaching with Tractate Parah] was Eliezer. A certain stranger questioned Rabban Johanan ben Zakkay, “These things which you do seem like a kind of sorcery.⁹³Numb. R. 19:8; PRK 4:7; PR 14:14. You bring a heifer, burn it, pound it, and take its ashes. Then [when] one of you is defiled by a corpse, they sprinkle two or three drops on him, and you say to him, ‘You are clean.’” He said to him, “Have you ever had a bad spirit of madness enter you?” He told him, “No.” He said to him, “Perhaps you have seen someone into whom a bad spirit has entered?” He told him, “Yes.” He said to him, “So what did you do for him?” He said to him, “They bring roots and burn them beneath him. Then they sprinkle water on [the spirit], and it flees.” He said to him, “Let your ears hear what you are uttering with your mouth. Similarly is this spirit an unclean spirit. Thus it is stated (in Zech. 13:2), ‘and I will also remove the prophets and the unclean spirit from the land.’ They sprinkle the purifying water upon him, and he flees.” After the gentile had left, [R. Johanan's] disciples said to him, “Our master, you repelled this one with a [mere] reed [of an answer]. What have you to say to us?” He said to them, “By your lives, a corpse does not defile, nor does a heifer purify, nor does water purify. Rather, the Holy One, blessed be He, has said, ‘I have enacted a statute for you. I have issued a decree, [and] you are not allowed to transgress against my decree.’” Thus it is written (in Numb. 19:2), “This is the statute of the Torah.” And for what reason are all the sacrifices male and female, while that one is [only] female?⁹⁴PRK 4:8. R. Ayyevu said, “It is comparable to the son of a female slave who defiled a king's palace.⁹⁵Lat.: praetorium Gk.: praitoriom. The king said, ‘Let his mother come and clean up the excrement.’ Similarly has the Holy One, blessed be He, said, ‘Let a heifer come and atone for the incident of the [golden] calf.’”

...R. Acha in the name of R. Chanina said: At the time when Moses ascended to the heavenly heights, he heard the voice of the Holy One, Blessed Be He, who was sitting and studying the [Torah portion of] the Red Heifer, and uttering a halakhah in the name of the one who spoke it. "R. Eliezer said: a calf [when written in the Torah] is one year old, and a cow is two [years old]." [Moses] said before Him: "Master of All the Worlds! May it be Your will that he [R. Eliezer] would be from my loins [i.e. would be my descendant]." [God] said to him: "By your life [i.e. assuredly] he is from your loins! For so it says in Scripture (Exodus 18:4): "...and the name of the other [son of Moses] was 'Eliezer'...", the same particular name.

R. Jose bar Hanina said: His (Moses') implication (in Numb. 19:2) was that all heifers perish, but his lasts forever. R. Aha said in the name of R. Jose bar Hanina: When Moses ascended into the firmament, he heard the voice of the Holy One sitting and being occupied with the parashah of the <Red Heifer>, and he was reciting a halakhah (i.e., a passage of Oral Torah) in the name of its author (from Parah 1:1): R. ELIEZER SAYS: THE CALF <WHOSE NECK IS TO BE BROKEN>¹²²See Deut. 21:3-4. IS TO BE ONE YEAR OLD, BUT THE <RED> HEIFER IS TO BE TWO YEARS OLD.¹²³See Braude’s translation of PR, 14:13 p. 290, n. 91, which records a suggestion of Mordecai Margulies, who notes that R. Eliezer would have begun his instruction with this mishnah. Moses said, Sovereign of the World, do not the realms above and below belong to you? Now you are citing a halakhah in the name of flesh and blood! He said to him: A righteous person is going to arise in my world and is first going to begin <his teaching> with the parashah of the <Red> Heifer: R. ELIEZER SAYS: THE CALF <WHOSE NECK IS TO BE BROKEN> IS TO BE ONE YEAR OLD, BUT THE <RED> HEIFER IS TO BE TWO YEARS OLD. He to him: Sovereign of the World, may it be <your> will that he come from my loins. He said to him: By your life, he is to be from your loins. Thus it is stated (of Moses' offspring in Exod. 18:4): AND THE NAME OF THE ONE¹²⁴So literally. In the biblical context the translation would normally read: AND THE NAME OF THE OTHER WAS ELIEZER. ELIEZER, <i.e.,> the name of that particular Eliezer, <who would begin his Mishnah teaching with tractate Parah>.
