Midrash sa Job 38:9: Pirkei DeRabbi Eliezer & Vayikra Rabbah

The dwelling of the moon is between cloud and thick darkness made like two dishes turned one over the other, and when it is the conjunction of the moon these two clouds turn in the east quarter and (the moon) goes forth from between them like a ram's horn. On the first night (is revealed) one measure (of light), on the second night the second measure, and so on until the half of the month when the moon is fully revealed, and from the middle of the month these two clouds turn their faces in the west quarter. The corner (i.e. crescent) of the moon with which it comes forth first, (the same) begins to enter and is covered therein by the two (clouds) on the first night (by) one measure, on the second night (by) a second measure, and so on to the end of the month until || it is entirely covered. And whence do we know that it is placed between two clouds? Because it is said, "When I made the cloud the garment thereof, and thick darkness a swaddlingband for it" (Job 38:9). And whence do we know that it becomes entirely covered? Because it is said, "Blow ye the trumpet in the new moon, at the covering, on our solemn feast day" (Ps. 81:8). "At the covering," on the day when it is entirely covered, blow ye the trumpet in the new moon.

Another matter, “when a woman conceives” – that is what is written: “Who dammed the sea with doors when it burst out and emerged from the womb” (Job 38:8). Rabbi Eliezer, Rabbi Yehoshua, and Rabbi Akiva, Rabbi Eliezer says: Just as there are doors to a house, so there are doors to a woman. That is what is written: “For it did not shut the doors of my belly” (Job 3:10). Rabbi Yehoshua says: Just as there are keys [mafteḥot] to a house, the same is true of a woman. That is what is written: “God remembered Rachel, and God heeded her, and He opened [vayiftaḥ] her womb” (Genesis 30:22). Rabbi Akiva says: Just as there are hinges [tzirim] for a house, so there are hinges foe a woman. That is what is written: “She crouched and gave birth, as her pangs of labor [tzireha] overcame her” (I Samuel 4:19). “When it burst out and emerged from the womb” – it is because it arrogantly seeks to emerge.
“When I placed a cloud as its garment” (Job 38:9), this is the fetal sac. “And fog as its swaddling” (Job 38:9), this is the placenta. “I imposed My limitations upon it” (Job 38:10), these are the first three months. “And I set a bar and doors” (Job 38:10), these are the three middle months. “I said: You shall come this far and not continue” (Job 38:11), these are the final three months. “And here the foam of your waves [bigeon galekha] will be set” (Job 38:11), Rabbi Aivu said: Due to your ordure [beon gelalekha],¹⁴Several commentaries write that the text should state “Your ordure is the object of pride [bigeon gelalekha]" (Rabbi David Luria; Etz Yosef). as when this fetus emerges, it emerges covered with ordure and all kinds of fetid substances, yet everyone hugs it and kisses it, especially if it is male. That is what is written: “When a woman conceives and bears a male child.”¹⁵The point here is that one should contemplate and thank God for the entire process that begins at conception and continues until birth.
