Midrash sa Job 28:28: Shemot Rabbah, Ein Yaakov (Glick Edition), Midrash Tanchuma & Midrash Tanchuma Buber

The midwives said to Pharaoh: Because the Hebrew women are not like the Egyptian women, as they are vigorous; before the midwife comes to them, they have delivered (Exodus 1:19).
“As they are vigorous [ḥayot].” If you say that they are midwives,³²One of the interpretations of the Hebrew word ḥaya is midwife. does one midwife not require another midwife to assist her? Rather, this is what they said to him: This nation is analogized to the beasts of the field, which do not require midwives. Judah is likened to a lion, as it is written: “Judah is a lion’s cub (Genesis 49:9); Dan, “Dan will be a serpent [on the road]” (Genesis 49:17); Naftali, “a hind let loose” (Genesis 49:21); Issachar is “a strong-boned donkey” (Genesis 49:14); Joseph, “a firstborn bull” (Deuteronomy 33:17); Benjamin is “a wolf that claws” (Genesis 49:27). Regarding the rest it is written: “How your mother was a lioness, she lay among lions” (Ezekiel 19:2).
God was good to the midwives; the people increased and they grew very mighty (Exodus 1:20).
“God was good to the midwives.” What was this good? The king of Egypt accepted their explanations and did not harm them.
Alternatively, “God was good,” Rabbi Berekhya said in the name of Rabbi Ḥiyya ben Rabbi Abba: That is what is written: “He said to man: Behold, fear of the Lord, that is wisdom” (Job 28:28). What is the reward for fear? It is Torah. Because Yokheved feared the Holy One blessed be He, He produced Moses, of whom it is written: “That he was good” (Exodus 2:2), from her. And the Torah, that is called “a good acquisition” (Proverbs 4:2), was given through him, and it is called after his name, as it is stated: “Remember the Torah of Moses My servant” (Malachi 3:22).
As for Miriam, Betzalel, who was filled with wisdom, as it is written: “I filled him with the spirit of God, [with wisdom]” (Exodus 31:3), emerged from her. And he crafted an ark for the Torah, which is called “good” – that is: “God was good to the midwives.”
“The people increased,” to fulfill what is stated: “Who is it who says and it is realized, if the Lord did not command it?” (Lamentations 3:37). If Pharaoh commanded to kill all the males, to what avail was his decree when God did not command it? Rather: “The people increased and they grew very mighty.”

Resh Lakish said: "What is meant by the passage (Is. 33, 6.) And the stability of thy times and the strength of thy happiness shall be wisdom and knowledge; the fear of the Lord is his treasure, i.e., The stability, alludes to the Order of Zerain. Of thy time, refers to the Order of Moed; The strength, refers to the Order of Nashim; Of thy happiness, alludes to the Order of Nezikin; Shall be wisdom, refers to the Order of Kadshim; And knowledge, alludes to the Order of Taharoth. And after all these, The fear of the Lord [shall be] his treasure." Rabba said: "When a man is brought to Judgment [after he dies] he is asked: 'Hast thou dealt honestly? Hast thou had regular time for the study of the Torah? Hast thou married? Hast thou waited for salvation (Messiah)? Hast thou been a searcher after wisdom? Hast thou [cultivated thy mind to] conclude (to bring out one thing from another)?' And after all these if The fear of the Lord is his treasure, it (His Torah) counts; if not, it does not count. It is likened to the man who said to his messenger: 'Bring up to the upper floor a Kur of wheat.' The messenger went and when he had brought it up the man asked of him: 'Hast thou mixed a Kab of the Sand of Chumta in it?' 'No,' answered the messenger. Whereupon the master said: 'It were better if thou hadst not brought it up altogether.' " It was taught in the academy of R. Ishmael that a man has the right to mix a Kab Chumtin in every Kur of crop and he need not worry [in fear of doing wrong, for the sand preserves the crop]. Rabba b. R. Huna said: "Whoever possesses knowledge of the Torah without having (Ib. b) fear of the Lord is likened unto a treasurer who has been entrusted with the inner keys [of the treasury] but from whom the outer keys were withheld." R. Janai announced: "Oh, for him who has no courtyard but makes a gateway for his court!" R. Juda said: "The world would not have been created by the Holy One, praised be He! if not for the purpose that people should fear Him, for it is said (Ecc. 3, 14.) And God hath so made it that man should be afraid of Him." R. Simon and R. Elazar were sitting; they noticed that R. Jacob b. Acha was walking and passing by them. "Let us stand up before a man who fears sins." said one, to which the other replied: "Let us get up before a man who is a great scholar." Whereupon the former remarked to the latter: "I tell thee to get up before a man who fears sins and thou sayest to me to get up before a man who is a great scholar." It may be deduced [from the following] that the one who said "For a man who fears sins," was R. Elazar, for R. Jochanan in the name of R. Elazar said: "The Holy One, praised be He! has nothing [better] in His world but fear of Heaven, as it is written (Deu. 10, 12.) And now, Israel, what doth the Lord thy God require of thee, but to fear the Lord thy God. It is also written (Job 21, 28.) And he said unto the man. Behold, the fear of the Lord, that is wisdom. And in Greek Hen means one. The deduction is correct.

Because the midwives feared God (ibid., v. 21).¹¹See Sotah 11b. Tradition tells us that the two mid-wives, Shipra and Puah, were really Miriam and Jochebed. See Exodus Rabbah 1:13. How did the Holy One, blessed be He, reward them? He gave them houses. What houses did he give them? The house of priesthood and the house of kingship. Jochebed received priesthood and kingship, since Aaron became the high priest and Moses became a king: There was a king in Jerusalem (Deut. 33:5). What reward did Miriam receive for herself? Wisdom, as is said: The fear of the Lord is wisdom (Job 28:28), and it is written about Bezalel: And He hath filled him with the spirit of God, for he descended from her.
