Génesis 4:16 Midrash: Midrash Lekach Tov, Midrash Tanchuma Buber, Esther Rabbah & Devarim Rabbah

And Israel settled in Shittim. Balak and all his people of Pethor took counsel and said, "We have no choice but to seek the advice of Balaam." Balaam... Balaam gave his advice. Balak came to curse the people of Israel. It is written in one place (Joshua 24:9), "And he fought against Israel." And in another place (Judges 11:17), "If we fight with them." But he came to fight, and it did not go well. Immediately they went and entrusted their daughters, as our sages said regarding the "remembered above" matter. Therefore, it is said, "And Israel settled in Shittim, and the people began to commit sexual immorality with the daughters of Moab." And it says (Numbers 31:16), "These caused the children of Israel to sin." Weren't they brought from Midian? Rather, it teaches us that Midian and Moab were in this advice that Balaam gave in order to cause Israel to stumble. When Israel saw that Balaam had no power to curse them, they immediately fell into immorality, and 24,000 of them perished. "In Shittim" means that they engaged in foolishness. As it is also said (Proverbs 7:7), "The adulterous woman lacks sense." Another interpretation: "And Israel settled in Shittim." Whenever the term "settling" is mentioned, it is a language of distress. It is said regarding Cain (Genesis 4:16), "And Cain went out from the presence of the Lord and settled in the land of Nod." (Genesis 37:1) "And Jacob settled." Joseph was sold. (Exodus 32:6) "And the people sat down to eat and drink." And they handed over Joseph. (Exodus 32:6) "And the people sat down to eat and drink, and they got up to play." And Israel settled in Shittim, and there were deaths, and the people began to commit sexual immorality with the daughters of Moab. They made profane what was once holy. "The daughters of Moab" refers to the plains of Moab on the eastern side of the Jordan. For the wilderness of Jeshimon is to the west of the land of Moab, close to the Jordan, as it is a day's journey.

(Deut. 4:41:) THEN MOSES SET APART THREE CITIES <ON THE OTHER SIDE OF THE JORDAN > TOWARD THE RISING OF THE SUN. All murderers flee eastward. Thus it is stated (in Gen. 3:24): AND AT THE EAST OF THE GARDEN OF EDEN HE POSTED <THE CHERUBIM>. Cain fled to eastward, as stated (in Gen. 4:16): AND CAIN WENT OUT FROM BEFORE THE LORD AND DWELT IN THE LAND OF NOD, EAST OF EDEN.

“Was [haya] [a Judean man in the Shushan citadel]….” Rabbi Yoḥanan said: Everyone about whom “haya” is stated, it is he at the beginning and it is he at the end.⁹ He was righteous from beginning to end. They objected to him; but isn’t it written: “One was [haya] Abraham” (Ezekiel 33:24)?¹⁰ Abraham began his life as an idolater; he wasn’t the same at the beginning and the end. He said to them: That is not, in fact, a refutation, as Rabbi Ḥanina and Rabbi Yoḥanan said: At age three Abraham identified his Creator. That is what is written: “Because [ekev] Abraham heeded My voice” (Genesis 26:5). The number of years that Abraham heeded the voice of his Creator is the equivalent of ekev (172),¹¹Ayin – 70, kof –100, beit – 2 and he lived one hundred and seventy-five years. [If one does not accept this explanation,] how do I find expression for haya about him? It means that he was fated from the beginning to guide the entire world to repent.¹²Although Abraham was not a believer in God his whole life, he had the potential from the beginning.
“[The Lord God said:] Behold, the man has become [haya] [like one of us, knowing good and evil]” (Genesis 3:22) – he became fated to die. “The serpent was [haya] more cunning” (Genesis 3:1) – he was fated for punishment. “Cain was [haya] a cultivator of the ground” (Genesis 4:2) – he was fated for exile, as you say: “Cain departed from the presence of the Lord” (Genesis 4:16); saying that he would be “restless and wandering” (Genesis 4:12). “There was [haya] a man in the land of Utz” (Job 1:1) – he was fated for suffering. “Noah, a righteous man, was [haya] faultless” (Genesis 6:9) – he was fated to acknowledge his Creator. “Moses was [haya] herding (Exodus 3:1) – he was fated for salvation. Mordekhai was fated for redemption.
Rabbi Levi and the Rabbis: Rabbi Levi said: Anyone about whom haya is stated witnessed a new world. Rabbi Shmuel bar Naḥman said: They are five.
Noah – yesterday “Water eroded stone” (Job 14:19), as Rabbi Levi said in the name of Rabbi Yoḥanan: Even millstones were dissolved during the flood, and now [after the flood] it says: “The sons of Noah who emerged from the ark…” (Genesis 9:18),¹³Immediately following this verse, the Torah relates how the earth was repopulated by Noah’s sons while Noah was alive. indicating that he witnessed a new world.
Joseph – yesterday “they tortured [his feet] with chains” (Psalms 105:18), and now “And Joseph was [haya] was the ruler over the land” (Genesis 42:6); that is, he witnessed a new world.
Moses – yesterday he was fleeing from Pharaoh and now he is drowning him in the sea; that is, he witnessed a new world.
Job – yesterday “He spills my bile onto the ground” (Job 16:13), and now “and the Lord gave Job double what he had had” (Job 42:10); that is, he witnessed a new world.
Mordekhai – yesterday “he wore sackcloth and ashes” (Esther 4:1), and now “he emerged from before the king in royal garments” (Esther 8:15).
“And his name was Mordekhai” (Esther 2:5). Just as myrrh [mor] is first of all the spices,¹⁴It is first on the list of ingredients of the sacred oil of anointment (Exodus 30:23). so was Mordekhai first among the righteous in his generation.
