Midrash su Genesi 39:12

“He said: Blessed are you of the Lord, my daughter; you have shown more kindness at the end than at the beginning, not to follow the youths, whether poor or wealthy” (Ruth 3:10).
“At midnight I will rise to thank You because of Your righteous ordinances” (Psalms 119:62). Rabbi Pinḥas in the name of Rabbi Eliezer ben Yaakov: A harp and a lyre were placed alongside David’s head and when midnight would arrive he would rise and play them. Rabbi Levi said: A harp was suspended…²⁰⁸A north wind would blow and play the harp at midnight, awakening David, who would then arise and study Torah until morning (Eikha Rabba 2; Berakhot 3b). “Because of Your righteous ordinances [mishpetei tzidkekha]” – the punishments [shefatim] that you brought upon Pharaoh, as it is stated: “The Lord afflicted Pharaoh with great afflictions” (Genesis 12:17), and the kindnesses [tzedakot] that You performed for Abraham and Sarah.
Alternatively, “because of Your righteous ordinances” – the punishments that You brought upon the Egyptians, and the kindnesses that You performed with our ancestors in Egypt. They had no mitzvot in whose performance they could engage so they could be redeemed, and You gave them two mitzvot in which they could engage and be redeemed, and they are: The blood of the paschal offering and the blood of circumcision. Rabbi Levi said: On that night the blood of the paschal offering was mixed with the blood of circumcision, [and this allowed the Israelites to be redeemed,] as it is stated: “I passed by you, and saw you wallowing in your blood, I said to you: In your blood, live; I said to you: In your blood, live” (Ezekiel 16:6).
Alternatively, “because of Your righteous ordinances” – the punishments that You brought upon the Ammonites and Moavites, and the kindnesses that You performed with my grandfather and grandmother,²⁰⁹The verse in Psalms was stated by David, a descendant of Boaz and Ruth. as had he [Boaz] quickly uttered one curse to her, from where would I have descended? But You inspired him to bless her, as it is stated: “Blessed are you of the Lord, my daughter.”
“The trembling of man brings a snare; but one who trusts in the Lord will be exalted” (Proverbs 29:25). Rabbi Akiva was departing to Rome, [and] he said to a member of his household: ‘Go purchase for me an item that is equally appreciated by all.’ He went and brought him birds. [Rabbi Akiva] said to him: ‘Why did you take so long? [Did it take a long time] to trap them?’ He said: ‘It is because they cause people to tremble.’ [Rabbi Akiva] read this verse in his regard: “The trembling of [ḥerdat] man brings a snare.” The trembling that Jacob induced in Isaac, as it is written: “Isaac trembled [vayeḥerad] a great trembling…” (Genesis 27:33), and by right, he should have cursed him. “But one who trusts in the Lord will be exalted” – You inspired him to bless him, as it is stated: “And he shall be blessed” (Genesis 27:33).
The trembling that Ruth induced in Boaz, as it is stated: “The man trembled and flinched” (Ruth 3:8), and by right, he should have cursed her. “But, one who trusts in the Lord will be exalted” – You inspired him to bless her, as it is stated: “Blessed are you of the Lord, my daughter.” “And flinched,” she embraced him like lichen.²¹⁰She did so to calm him. He began touching her hair; he said: ‘Spirits do not have hair.’ He said to her: ‘Who are you, a spirit or a woman?’ She said: ‘A woman.’ [He said:] ‘Are you single or married?’ She said to him: ‘Single.’ [He said:] ‘Are you ritually impure, or pure?’ She said to him: ‘Pure.’ Here was a ritually pure woman lying at his feet, as it is stated: “He said: Who are you? She said: I am Ruth your maidservant…” (Ruth 3:9). Rabbi Berekhya said: The wicked are accursed. There it is written: “She grabbed him by his garment, saying: Lie with me” (Genesis 39:12), but here: “Spread your garment over your maidservant” (Ruth 3:9).²¹¹The wife of Potiphar brazenly demanded that Joseph lie with her, although she was married. Ruth, in contrast, who was permitted to Boaz, spoke to him in a humble and modest fashion.

(Ibid. 29) "and the children of Israel walked in the dry land (that had already been made) in the midst of the sea." R. Shimon b. Yochai says: The sun and the moon testify that I have already split the sea for them, viz. (Jeremiah 31:35) "Thus said the L rd who gives the sun for light by day, the laws of moon and stars for light by night, who splits the sea and stuns its waves — the L rd of hosts is His name." R. Bana'ah says: In the merit of the mitzvoth performed by Abraham I will split the sea for them, viz. (Genesis 22:3) "and he split the wood for the burnt-offering" — and here (Exodus 14:21) "and the waters were split." R. Shimon Hatemani says: In the merit of circumcision I will split the sea for them, viz. (Jeremiah 33:25) "If not for My covenant, day and night, I would not have made the statutes of heaven and earth." Which covenant obtains both day and night? Circumcision. R. Avshalom the elder says: An analogy: A man gets angry with his son and drives him from the house. His lover comes in to beseech him to restore him to his house. He responds: Are you beseeching me for my son? I have already come to terms with my son. Thus, the L rd: "Why do you cry out to Me?" I have already come to terms with them." Rebbi says: Last night you said (i.e., you complained to Me) (Exodus 5:23) "And from the time I came to Pharaoh, etc." And now you stand and wax long in prayer? "Why do you cry out to Me?" Rebbi says (Exodus 14:15) "Speak to the children of Israel and have them go forward ('veyisa'u')." Have them retract ('yasiu') the things that they said. Last night they said (Ibid. 11) "Is it for lack of graves, etc.?" and now you stand and wax long in prayer (for them)? "Why do you cry out to Me?" Let them retract what they have said. The sages say: He wrought with them for His name's sake, viz. (Isaiah 48:11) "For My sake, for My sake shall I do, etc." And (Ibid. 63:12) "He split the sea before them." Why? (Ibid.) "To make Himself an eternal name." Rebbi says: Their faith in Me suffices Me to split the sea for them. As it is written (Exodus 14:2) "Let them return and encamp, etc." R. Elazar b. Azaryah says: In the merit of their father Abraham I will split the sea for them, viz. (Psalms 105:42) "For He remembered His holy word to Abraham His servant. (43) And He led out His people with joy, etc." R. Eliezer b. Yehudah of Bortutha says: In the merit of the tribes I will split the sea for them, viz. (Habakkuk 3:14) "You have split (the sea) for his tribes, the heads of his scattered ones, etc." And it is written (Psalms 136:13) "who split the sea into sections." Shmayah says: The faith that Abraham their father had in Me suffices for Me to split the sea for them, viz. (Exodus 4:31) "And the people believed when they heard, etc." Shimon of Kitron says: In the merit of the bones of Joseph I will split the sea for them, viz. (Genesis 39:12) "And he left his garment in her hand and he fled." And it is written (Psalms 114:3) "The sea saw and it fled, etc." R. Nathan says in the name of Abba Yossi Hamechuzi: ("Why do you cry out to Me?") Have I not had it written (Numbers 12:7) "In all of My house he (Moses) is trusted"? You (Moses) are in My dominion and the sea is in My dominion, and I have appointed you a keeper over it. (Therefore, [Exodus 14:16] "Raise your staff, etc.") R. Chanina b. Chachinai says: Have I not had it written (Mishlei 17:17) "A brother is born for (times of) trouble"? I am a brother to Israel in their time of trouble. "Brother" (here) signifies Israel, viz. (Psalms 122:8) "For the sake of My brothers and My friends I will speak for peace in you (Jerusalem)." R. Shimon b. Yehudah says: "Why do you cry out to Me?" Their cries have already preceded yours, viz. (Exodus 14:10) "and the children of Israel cried out to the L rd, etc." R. Acha says: The Holy One Blessed be He said: If not for your outcry, I would have destroyed them for the idolatry in their midst, viz. (Zechariah 10:11) "And tzarah crossed the sea," tzarah (here) being idolatry, as in (Isaiah 28:20) "and the molten image, tzarah, etc." and as in (Leviticus 18:18) "And a woman to her sister do not take litzror" (to be a rival). And because of your outcry I have withdrawn My wrath, as it is written (Psalms 106:22-23) ("… awesome deeds at the Red Sea) and he thought to destroy them if Moses His chosen one had not stood in the breach before Him, to turn His wrath from destruction." R. Eliezer Hamodai says: "Why do you cry out to Me?" I do not have to be commanded for the children of Israel, (Isaiah 45:11) "For My children and the work of My hands would you command Me?" Are they not "readied" before Me from the six days of creation? (Jeremiah 31:36) "Just as these laws (of nature) will not depart from before Me, says the L rd, so the children of Israel will not cease from being a nation before me for all time." Others say: The faith that they had in Me suffices for Me to split the sea for them. They did not say to Moses: How can we go out to the desert without food? But they believed in Moses and followed him. Of this it is written in the Tradition (Jeremiah 2:2) "Go and call out in the ears of Jerusalem, saying … I have remembered for you the lovingkindness of your youth, the love of your espousals, your following Me in the desert, in a land unsown." How were they rewarded for this? (Ibid. 3) "Holy is Israel unto the L rd, the first of His harvest. All of its eaters will be blamed. Evil will come upon them, says the L rd." R. Yossi Haglili says: When Israel entered the sea, Mount Moriah was uprooted from its place, with the altar of Israel built upon it, and its woodpile upon it, and Isaac bound upon it upon the altar, and Abraham stretching out his hand and taking the knife to slaughter his son — whereupon the L rd said to Moses: Moses, My children are in trouble, the sea raging and the foe pursuing them, and you stand and indulge in prayer? Moses: But what can I do? The L rd: "Raise your staff and stretch out your hand over the sea, etc." And you — exalt and praise and accord song and praise and thanks and grandeur and glory and splendor and hallel to the Master of wars!

“Whose [heart] is snares and nets” – as she traps in the sea and on dry land. “Her hands, shackles,” Rabbi Elazar said: Had he not written in her regard: “Her hands, shackles,” she would seize a man in the marketplace and say: ‘Have relations with me.’¹⁴¹The midrash interprets the verse to mean that the woman’s hands are shackled, meaning that she is too inhibited to demand relations outright. Instead, her “heart is snares and nets” – in her heart she desires relations, and she finds ways to entice men. This is analogous to a biting dog whose owner holds it on a chain; even though it is tied, it would grasp onto a person in the marketplace by his clothes. So, had he not written in her regard: “Her hands, shackles,” she would abduct a person in the marketplace. See what is written: “She seized him by his garments, saying: Lie with me” (Genesis 39:12). “One who is good before God will escape from her” – this is Joseph; “but the sinner will be captured by her” – this is Potifar. Alternatively, “good” – this is Pinḥas, “but the sinner” – this is Zimri. Alternatively, “good” – this is Palti, “but the sinner” – this is Amnon.
Rabbi Isi of Caesarea interpreted the verse regarding heresy. “Good” – this is Rabbi Elazar, “but a sinner” – this is Yaakov of the village of Nevurya.¹⁴²He was a heretic. Alternatively, “good” – this is Elazar ben Dama, “but a sinner” – this is Yaakov of the village of Sama.¹⁴³See Kohelet Rabba 1:8 for a story pertaining to Elazar ben Dama and Yaakov of Sikhanya, who some commentaries equate with the Yaakov of Sama mentioned here. The midrash there also mentions the other individuals identified here as good or as heretics. Alternatively, “good” – this is Ḥananya, son of Rabbi Yehoshua’s brother, “but a sinner” – these are the residents of the village of Naḥum.¹⁴⁴These heretics employed sorcery to apprehend Ḥananya, but Rabbi Yehoshua rescued him; see Kohelet Rabba 1:8. Alternatively, “good” – this is Yehuda ben Nekosa, “but a sinner” – these are the heretics. Alternatively, “good” – this is Rabbi Natan, “but a sinner” – this is his disciple.¹⁴⁵He went and joined the heretics. Alternatively, “good” – this is Rabbi Eliezer and Rabbi Yehoshua, “but a sinner” – this is Elisha.¹⁴⁶Elisha ben Avuya, who ultimately adopted a sinful path.
