Midrash for Exodus 34:2

But the tender mercies of the wicked are cruel (Prov. 12:10). This verse alludes to the men of the generation of the flood, who were extremely cruel. Our rabbis of blessed memory posed the query: What did they do when the Holy One, blessed be He, brought the waters of the deep upon them and they saw the waters beginning to gush over them? They had given birth to many children, as it is written: Their seed is established (nakhon) in their sight with them, and their offspring before their eyes (Job 21:8). In fact, this verse implies that the women would conceive at night and give birth (nakhon) the next morning, as it is said: And would be ready (nakhon) by morning (Exod. 34:2). And their offspring before their eyes (Job 21:8) indicates that they lived to see their great-grandchildren. Some of them took their children and stuffed them unmercifully into the crevices through which the waters gushed. Hence, it is said: The mercies of the wicked are cruel. How do we know that they actually did that? Job declared: The womb forgetteth him; the worm feedeth sweetly on him; he shall be no more remembered, unrighteousness is broken as a tree (ibid. 24:20). The womb forgetteth him … he shall be no more remembered signifies that they pressed their own offspring into these crevices. What did the Holy One, blessed be He, do to them after that? He brought the flood down upon them and destroyed them, as it is said: Unrighteousness is broken as a tree.¹³Just as a tree is destroyed by a flood, so these unrighteous men were destroyed by the flood from above.

Another matter, “My beloved is like a gazelle,” Rabbi Yitzḥak said: The congregation of Israel said before the Holy One blessed be He: ‘Master of the universe, You said to us: Come, come. You come to us first.’
“My beloved is like a gazelle,” just as this gazelle leaps from mountain to mountain, from valley to valley, from tree to tree, from booth to booth, and from fence to fence, so too, the Holy One blessed be He leaps from this synagogue to that synagogue, from this study hall to that study hall. Why to that extent? In order to bless Israel. By what merit? By the merit of Abraham; that is what is written: “The Lord appeared to him at the terebinths of Mamre [and he was sitting at the entrance of the tent]” (Genesis 18:1). Rabbi Berekhya [said] in the name of Rabbi Levi: “Was sitting [yoshev],” [the word] yoshev is written without a vav.¹⁰³This indicates that there was something incomplete about his sitting, because he had begun to get up (Etz Yosef). Abraham sought to stand, [but] the Holy One blessed be He said to him: ‘Sit, Abraham, you are a model for your descendants. Just as you are sitting and I am standing, so will it be for your descendants when they enter the synagogue and the study hall and recite Shema; they will be sitting, and My glory will stand in their midst.’ What is the source? “God stands [nitzav] in the congregation of God” (Psalms 82:1). Rabbi Ḥagai said in the name of Rabbi Yitzḥak: “God stands [omed]” is not written, but rather, nitzav. What is nitzav? It is standing at the ready, just as it says: “You shall stand [venitzavta] there for Me atop the mountain” (Exodus 34:2), and it is written: “It will be, before they call [I will answer, while they yet speak I will hear]” (Isaiah 65:24).¹⁰⁴This indicates that God stands at the ready, anticipating Israel’s prayers. Rabbi Shmuel in the name of Rabbi Ḥanina: With each and every praise with which Israel lauds the Holy One blessed be He, the Holy One blessed be He sits in their midst, as it is written: “You are holy, sitting upon the praises of Israel” (Psalms 22:4).
“Or a fawn,” Rabbi Yosei bar Ḥanina said: Like the offspring of a hind. “Behold, he is standing behind our wall,” behind the walls of synagogues and study halls. “Gazing through the window,” from between the priests’ shoulders. “Peering through the lattice,” from between the priests’ fingers. “My beloved spoke up, and he said to me” (Song of Songs 2:10), what did He say to me? “May the Lord bless you and keep you” (Numbers 6:24).

"The sons of Noah who came out of the ark were Shem, Ham, and Japheth (Genesis 9:18)": "When He is silent, who will condemn? If He hides His face, who will see Him, Be it nation or man? (Job 34:29)". Rabbi Meir interpreted: ""He is silent" from his world, and "He hides his face" from his world, like a judge whom a curtain stretches in front of his face and he does not know what is being done beyond it. Likewise they said about the generation of the Flood: "The clouds screen Him so He cannot see as He moves about the circuit of heaven (Job 22:14)"". They said to him: "That is enough for you, Meir". He said to them: "But why is it written: "When He is silent, who will condemn?"? He said: "Did he not give contentment to the generation of the Flood? And who came to reproach them. What contentment did he give them? "Their children are with them always [nakhon], And they see their children’s children (Job 21:8)", "They let their infants run loose like sheep, And their children skip about (Job 28:11)". Rabbi Levi and the Rabbis: Rabbi Levi said: "For three days one's wife was pregnant, as it is said elsewhere using the word nakhon "Be ready [nakhon] for the third day: do not go near a woman (Exodus 19:15)". As nakhon is said here to mean for three days, so nakhon is there for three days". And the Rabbis said: "For one day one's wife was pregnant and gave birth, as nakhon is said there and here: "Be ready [nakhon] by morning (Exodus 34:2)". As nakhon is said here to mean for one day, so nakhon is there for one day". "And they see": they were looking at their children and their children's children. "They let their infants ['avileihem] run loose like sheep": Rabbi Levi said: "In Arabia they call a child an avilah". "And their children skip [yeraqqedun] about": like demons, which is why it says: "And there shall satyrs dance [yeraqqedu] (Isaiah 13:21)". One of these women gave birth during the day, and she said to her son: "Go and bring me a flint to detach your umbilical cord". And at night she said to her son: "Go and light a lamp for me to detach your umbilical cord". There was a time when one gave birth at night and said to her son: "Go and light a lamp for me to detach your umbilical cord" and her son went and met with the demon Asmodeus. Asmodeus said to him: "Go and tell you mother that the rooster has crowed, and if the rooster had not crowed I would have harmed you". The boy said to him: "Go and tell you mother that my mother has not detached my umbilical cord, and if she had I would have struck and killed you." See! It is written: "Their homes are secure, without fear (Job 21:9)": from destroyers/demons. "They do not feel the rod of God (Job 21:9)": because of a lack of chastisement. Why did he hide his face from them? Because he brought to them the Flood. See! It is written: "All existence on earth was blotted out (Genesis 7:23)". "Be it nation or man together". "Be it nation": this is the generation of the Flood". "Or man": this is Noah. "Together": because from him the world was established, and it is possible for him to set up the world from a nation alone and from one man, as it is said: "The sons of Noah who came out of the ark".
