Midrash su Isaia 41:2

"Samuel wrote his book," but is it not written And Samuel died? The book was finished by Gad the seer and Nathan the Prophet. "David wrote his book with the help of the ten elders." Why did the Baraitha not enumerate also Ethan the Ezrachite? Rab said: "Ethan the Ezrachite is Abraham, for it is written here (Ps. 89, 1) Ethan the Ezrachite, and it is also written (Is. 41, 2) Who waked up from the East (Mimizrach)," etc. It enumerates Moses, and also Heiman; did not Rab say that Heiman means Moses, for it is written here Heiman and it is written (Num. 12, 7) In all my house is he (Ne'eman) faithful. There were two Heimans. "Moses wrote his book, the chapter of Bilam and Job." This verifies the statement of R. Levy b. Lachma, who said that Job lived in the time of Moses. Raba, however, said: "Job lived in the time of the spies who were sent by Moses to investigate Palestine, for it is written concerning Job (Job 1, 1) Utz, and dealing with the spies, Moses also mentions a word similar to this (Etz, a tree). But how can you say that Utz and Etz are the same? Moses thus said to Israel: "There is a man whose years are as numerous as that of a tree and who protects his generation like a tree protects its branches."

Rabbi Yehudah the son of Simon interpreted this reading as applying to generations: "and the earth was formless and void" (tohu vavohu), this is Adam the first, since he was made made entirely into nothing. "And void" (vavohu), this is Cain, who sought to return the world to "formlessness and void". And "darkness" (choshech), this is the generation of Enosh, on whom further [it says] "and their works were in darkness (bemach'shach)" (Isaiah 29:15) and they said "who is watching us and who will see us?". "On the face of the deep (tehom)", this is the generation of the flood, as it is said "On this day all the springs of the deep (tehom) were broken open" (Genesis 7:11). "And the spirit (ruach) of God fluttered over the face of the waters" on which it is further said "And God caused a wind (ruach) to pass over the earth" (Genesis 9:1). The Holy One, blessed be He, said: "how long shall the universe accustom itself to deep darkness? Let the light come!": "And Hashem said let there be light", this is Abraham. See! It is written "Who has raised (heʿir) up one from the east, righteousness" (Isaiah 41:2); do not read "raised up (heʿir with an ayin), but rather "illuminate" (heʾir with an alef). "And Hashem called the light 'day'", this is Jacob. "And the darkness he called night", this is Esau. "And it was evening", this is Esau. "And it was morning", this is Jacob. "And there was evening", the evening of Esau. "And there was morning", the morning of Jacob. "One day (yom echad)" as it is written "And there shall be one day (yom echad) which shall be known as the Hashem's, not day, and not night" (Zechariah 14:7). There is another issue with one day, that the Holy One, blessed be He, have him "one day", and what is this? Yom Kippur.

Another interpretation (of Gen. 28:10): AND JACOB SET OUT. This text is related (to I Sam. 2:9): HE SHALL PROTECT THE FEET OF HIS SAINTS. This refers to Abraham when he pursued the kings. Thus it is stated (in Is. 41:2): WHO HAS AROUSED < RIGHTEOUSNESS >⁵The word translated RIGHTEOUSNESS here (tsedeq) implies victory and success as well as righteousness. FROM THE EAST … ? (I Sam. 2:9, cont.:) BUT THE WICKED SHALL PERISH IN DARKNESS. These are the sixteen kings whom he killed in the darkness, as stated (in Gen. 14:15): THEN HE DEPLOYED < HIS FORCES > AGAINST THEM BY NIGHT.
