מדרש אויף ישעיהו 51:1

R. Chanina b. Papa raised a contradictory objection: "It is written (Is. 21, 14) Toward him that is thirsty bring water; and further it is written (Ib. 51, 1) Every one of ye that thirsteth, come ye to the water; this implies that if one is a worthy scholar, the passage applies: toward him that is thirsty bring water [the teacher should even go to him]; but if he is not a worthy scholar, then the passage applies: every one of ye that thirsteth, come ye to the water, [only if he comes to the master should he be taught.]" R. Chanina b. Chama pointed out another contradiction: "It is "written (Prov. 5, 16) Let thy springs overflow abroad; and further it is written (Ib. 17) They will be thy own only; implying that if one is a worthy scholar, [his teachings should be allowed] to spread abroad; but if not, they should remain his own only." R. Chanina b. Idi said: "Why are the words of the Torah compared to water? It is written (Is. 21, 14) Toward him that is thirsty bring water. This teaches that just as water runs down from a higher place to a lower one, so the words of the Torah can only be retained by one who possesses a humble mind [thinks of his shortcomings]." R. Oshiya said: "Why are the words of the Torah likened unto the three liquids — water, wine, and milk? It is written (Ib.) Toward him that is thirsty bring water; and it is written (Is. Iv. 1) Yea, come, buy without money and without price wine and milk. This is to teach you, that as those three liquids can best be kept in common utensils, such as wooden or earthen vessels, so the Torah can only be restrained by those who possess a humble mind." And it is this that the daughter of Caesar once said to R. Joshua b. Chanania: "O how unbecoming that ugly vessel with glorious wisdom!" Whereupon he said to her: "My daughter, in what does the king, your father, keep his best wine?" "In earthen vessels," was her answer. And he rejoined: "The common people keep it in earthen vessels, and your father also in earthen vessels, — how is that! "In what, then, shall it be kept?" she innocently asked. "You, who are wealthy," R. Joshua remarked, "ought to keep it in silver and golden vessels!" She then told her father, and he commanded that his wine should be kept in vessels of silver and gold. Consequently it became sour. When Caesar was informed of this, he asked his daughter: "Who told you to do so?" "R. Joshua b. Chanania," she answered. Thereupon the king sent for R. Joshua b. Chanania. "Why hast thou advised her so?" he was asked. And he rejoined: "This was only an answer to the question of the princess." "But are there not men who are handsome and at the same time very scholarly?" Caesar asked. (Ib. b) "Believe me," said the Rabbi, "had they been ugly, they would have been still greater scholars." Another explanation may be given [why the words of the Torah are likened unto water, wine and milk]. Just as these three liquids, [unlike honey or oil, which, on account of its thickness, can easily be separated if anything falls in to it], are apt to become spoiled through diverted attention [should anything fall into it], so also does the Torah become forgotten by diverting attention from it (i.e., by neglect of study).

[Exod. 38:21:) THESE ARE THE RECORDS OF THE TABERNACLE, THE TABERNACLE OF THE TESTIMONY.] What is the meaning of THE TESTIMONY? This is the Torah in which they would labor.¹⁸Tanh., Exod. 11:8; Exod. R. 51:7. The Holy One said to them: By virtue of the Torah and by virtue of the offerings, I am saving you from Gehinnom. Also in the case of their father Abraham, the Holy One showed him the Torah, the offerings, Gehinnom, and the empires (all of which were revealed to him in the theophany of Gen. 15):¹⁹PRK 5:2; PR 15:2; Gen. R. 44:21; M. Pss. 52:8; Mikhilta de Rabbi Ishmael, Bahodesh 9; cf. Lev. R. 13:5. Torah (in Gen. 15:17): AND A FLAMING TORCH;²⁰Cf. Exod. R. 51:7, which relates this verse to the lightning on Mt. Sinai in Exod. 20:15 [18]. the offerings (in vs. 9): AND HE SAID UNTO HIM: BRING ME A THREE-YEAR-OLD HEIFER; Gehinnom (in vs. 17): A SMOKING OVEN; the empires (in vs. 12): AND LO, A GREAT DARK DREAD <FELL UPON HIM>. The Holy One said to him: As long as your children are engaged in <the first> two, they shall be saved from <the other > two. As long as they are engaged in the Torah and the offerings, they shall be saved from Gehinnom and from the empires. Now the Temple is going to be destroyed, and the offerings shall cease. Therefore, how do you say that your children should be enslaved? By Gehinnom or by the empires? Abraham chose the empires. He said to him: Sovereign of the World, Let them be enslaved by the empires, and let not one of them go down into Gehinnom. Thus it is stated (in Deut. 32:30): <HOW SHOULD ONE HAVE ROUTED A THOUSAND, OR TWO PUT TEN THOUSAND TO FLIGHT, > UNLESS THEIR ROCK HAD SOLD THEM? Now THEIR ROCK can only be their father Abraham, since it is stated (in Is. 51:1): LOOK UNTO THE ROCK OUT OF WHICH YOU WERE HEWN. (Deut. 32:30, cont.:) AND THE LORD HAD GIVEN THEM UP, because the Holy One had concurred with him (i.e., with Abraham in his decision to be enslaved by the empires). R. Hanina said: Abraham was standing in bewilderment, and did not know what to choose. The Holy One said to him: Make the decision. At that time the Holy One gave him a hint to choose the empires.²¹According to Exod. R. 51:7, the hint is found in Ps. 66:12. See also Tanh., Exod. 11:8. Ergo (in Exod. 38:21): THESE ARE THE RECORDS OF THE TABERNACLE <…> OF THE TESTIMONY, <a testimony that> as long as Israel was engaged in the Torah and in the offerings, they would not go down into Gehinnom. The Holy One said to Israel: In this world you have been enslaved in the hands of empires, but in the world to come I will save you from Gehinnom by virtue of the Torah, which is called a fire, as stated (in Deut. 33:2): AT HIS RIGHT HAND THERE A FIERY LAW (dat) FOR THEM. So the fire (of Torah) puts out the fire (of Gehinnom), as stated (in Is. 43:2): WHEN YOU WALK THROUGH THE FIRE, YOU SHALL NOT BE SCORCHED, NEITHER SHALL THE FLAME BURN YOU.

R. Isaac said: "Our father Isaac was impotent, as it is said (Gen. 25, 21) And Isaac entreated the Lord (L'nochach) opposite his wife. It is not stated Al (concerning) his wife, but it is said L'nochach (opposite) his wife. Infer from this that both of them were impotent [and therefore both prayed."] If so, then why is it written: And the Lord was entreated of him? Entreated of them, it ought to be? This is because the prayer of a righteous (Isaac), the son of a righteous, is not like the prayer of a righteous (Rebecca), son (daughter) of a wicked. R. Isaac said: "Why were our ancestors childless [until they prayed?] Because the Holy One, praised be He! desires [to hear] the prayers of the righteous." R. Isaac said: "Why are the prayers of the righteous symbolized by a shovel? Because just as the shovel turns the grain at the threshing floor from place to place, so the prayers of the righteous turn the dispensations of the Lord from anger to mercy." R. Ami said: "Sarah our mother was a Tumtum, as it is said (Is. 51, 1) Look unto the rock, (Ib. b) whence ye were hewn, and to the hole of the pit whence they were dug out. And immediately follows: Look unto Abraham your father, and unto Sarah that bore you." 11. Nachman, in the name of Rabba b. Abahu, said: "Our mother Sarah was wombless, as it is said (Gen. 11, 30) But Sarah was barren, she had no child; i.e., even a place for a child (womb) she had not."
