La Genèse 15:12 Midrash : Midrash Tanchuma Buber, Midrash Tanchuma, Mekhilta DeRabbi Yishmael & Vayikra Rabbah

[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.

The tabernacle of the testimony (Exod. 38:21). This refers the Torah in which they labored. The Holy One, blessed be He, said: Because of the Torah and the sacrifices, I will rescue you from Gehinnom. You may know this from the fact that the Holy One, blessed be He, revealed to Abraham the Torah, the sacrifices, Gehinnom, and the servitude experienced by the exiles. The Torah: A flaming torch (Gen. 15:17), for it is written: At this hand was a fiery law unto them (Deut. 33:2), and the people perceived the thunder and lightning (Exod. 20:15); the sacrifices: Take me a heifer of three years (Gen. 15:9); Gehinnom: A smoking furnace and a flaming torch (ibid., v. 17); the servitude at the hands of the nations: For, behold, there was thick darkness (ibid.).

He showed him the four kingdoms that were destined to subjugate his children, viz. (Ibid. 12) "And when the sun was about to set, and a deep sleep fell upon Avram, and, behold, a great dark dread fell upon him": "dread" — the kingdom of Bavel. "dark" — the kingdom of Madai. "great' — the kingdom of Greece. "fell" — the wicked Rome. Some transpose it: "fell" — the kingdom of Bavel, viz. (Isaiah 21:9) "Bavel has fallen." "great" — the kingdom of Madai, viz. (Esther 3:1) "King Achashverosh made great, etc." "dark" — the kingdom of Greece, which darkened the eyes of Israel with afflictions. "dread" — the fourth kingdom, viz. (Daniel 7:7) "… fearful, dreadful, and of great strength."...
