Мидраш к Диврей ха-ямим Б 2:16

“Boaz said to his servant who was appointed over the reapers: Whose is this young woman?” (Ruth 2:5).
“Boaz said to his servant who was appointed over the reapers” – over how many was he appointed? Rabbi Eliezer bar Miriam said: He was appointed over forty-two, [as evident] from this [verse]: “Solomon counted all the strangers who were in the land of Israel…[and they were found to be one hundred fifty-three thousand, six hundred]. He set from them seventy thousand porters [and eighty thousand hewers in the mountains, and three thousand six hundred overseers to set the people at work]” (II Chronicles 2:16–17).¹⁶²Having 3,600 overseers for 150,000 workers yields a ratio of one overseer for approximately forty-two workers. One who does so can sustain it and know what each of them is doing.
“Whose is this young woman?” – did he not know who she was? Rather, once he saw that she was pleasant and her actions were fine, he began asking about her. All the women would bend at the waist and gather, and this one would sit and gather. All the women would raise their skirts, and she would lower her skirts. All the women would jest with the reapers, while she would conduct herself modestly. All the women would gather between the sheaves, and she would gather from what had been abandoned.
Similarly, “When Saul saw David emerge against the Philistine [he said to Avner, commander of the army: Avner, whose son is this lad?]” (I Samuel 17:55); did he not know who he was? The day before, he had sent to Yishai saying: “Please let David stand before me, as he has found favor in my eyes” (I Samuel 16:22), and now he is asking about him? Rather, when Saul saw the head of the Philistine in his hand, he began asking about him: If he descends from Peretz, he is a king. If he descends from Zeraḥ, he is a judge.¹⁶³Saul knew that David was from the tribe of Judah but did not know from which of Judah’s sons he descended, from Peretz or Zeraḥ. Apparently, there was a tradition that kings would descend form Peretz. Doeg the Edomite was there at that time, and said to him: Even if he descends from Peretz, is he not disqualified? Is he not of disqualified lineage; does he not descend from Ruth the Moavite? Avner said to him: Has the halakha of: An Amonite and not an Amonite woman, not been introduced? He said to him: If so, an Edomite and not an Edomite woman, an Egyptian and not an Egyptian woman.¹⁶⁴It is forbidden to marry an Edomite or Egyptian convert or his descendants, for three generations since his conversion (Deuteronomy 23:8–9). This is understood to apply to both male and female converts. Why were [Amonite and Moavite converts] barred? Was it not “because they did not meet you with bread and with water; [and they hired against you Bilam son of Beor from Petor, Aram Naharayim, to curse you]” (Deuteronomy 23:5)? The women should have gone out to the women [with bread and water]. Avner temporarily forgot the [reason for this] halakha. Saul said to him: The halakha that you forgot, go and ask Samuel and his court. When he came to Samuel in his court, he said to him: From where did you get this, was it not from Doeg? Doeg is a heretic and will not leave this world in peace. To send you away with nothing¹⁶⁵With no response to Doeg’s argument. is not possible. Rather, it is written: “All the glory of the king’s daughter is inside” (Psalms 45:14); it is not for a woman to go out, it is for a man to go out. “And they hired against you” (Deuteronomy 23:5) – it is for a man to pay wages and not for a woman.
“The servant that was appointed over the reapers answered and said: She is a Moavite young woman who returned with Naomi from the field of Moav” (Ruth 2:6).
“The servant that was appointed over the reapers answered and said: She is a Moavite young woman”; and you said her actions are fine and pleasant? Rather, her mentor cured her.¹⁶⁶Naomi cured her of her Moavite ways. This is derived from the continuation of the verse, “who returned with Naomi from the field of Moav” (Matnot Kehuna). The word returned [shava] can also mean “repented.”

... “And David went and he took the bones of Saul and the bones of Jonathan his son from the men of Jabesh- gilead… And he brought up from there the bones of Saul and the bones of Jonathan his son…” (Shmuel II 21:12-13) What did David do? He went and gathered all the elders and great ones of Israel, crossed the Jordan River, and came to Yavesh-gilead. He found the bones of Shaul and his son Yonatan, placed them in a casket and crossed back over the Jordan, as it says “And they buried the bones of Saul and Jonathan his son in the country of Benjamin in Zela, in the tomb of Kish his father and they did all that the king commanded…” (Shmuel II 21:14) What does ‘in Zela, in the tomb of Kish his father’ mean? It comes to teach us that they brought them to the border of Jerusalem and buried them there. Zela is next to Jerusalem, as it says “And Zelah, Eleph, and the Jebusite, which is Jerusalem…” (Yehoshua 18:28) ‘and they did all that the king commanded’ And what did the king command? He commanded that they carry Shaul’s casket from tribe to tribe. As Shaul’s casket entered each tribe’s territory all the men, women and children came out in order to perform an act of loving kindness to Shaul and his sons and thereby all of Israel would fulfill its obligation to loving kindness. This went on until they reached the land of his portion on the border of Jerusalem. Since the Holy One saw that they did loving kindness to Shaul and fulfilled the judgement of the Givonites He was immediately filled with mercy and sent rain upon the land, as it says “And God was entreated for the land after that.” (Shmuel II 21:14) From this we learn how close the Holy One brings those that are far away, even though they converted not for the sake of heaven. There is no need to even mention how he draws near righteous converts, “O Lord, all the kings of the earth will acknowledge You…” (Tehillim 138:4)

But behold it is written (Deut. 24, 26) Fathers shall not be put to death for the children, neither shall children be put to death for the fathers? R. Chiya b. Abba said in the name of R. Jochanan: "Rather let one word of the Torah become impotent, than have the Heavenly name publicly profaned." (II Sam. 21, 10) And Rizpah the daughter of Ayah took sack cloth, and spread it out for herself upon the rock, from the beginning of the harvest until water dropped down upon them out of heaven, and she suffered neither the birds of heaven to rest on them by day, nor the beasts of the field by night. Behold it is written (Deut. 21, 23) Then shall his body not remain all night on the tree. R. Jochanan in the name of R. Simon b. Jehozadak said: "It is worth while that one letter of the Torah become impotent, if only the Heavenly name should [through it] be sanctified publicly: [for, whoever passed by the corpse] asked: 'What is the nature of these? Are they not princes, and what [crime] have they committed?' Because they had raised their hands against self-made converts (not formally admitted),' [the reasons were given.] The inquirers then would remark: 'There is no other nation that is more fitting to be associated with than this (Israel); for, if to princes they gave such punishment how much more so to an ordinary man; and if they so protect self-made converts, how much more so will they protect real Israelites (duly admitted proselytes)?' The result therefrom was that Israel was increased by one hundred and fifty thousand [proselytes], as it is said (I King 5, 29) And there belonged to Solomon seventy thousand bearers of burdens, and eighty thousand stone cutters in the mountains." But perhaps these were Israelties? You cannot possibly think so, for it is written (Ib. 9, 22) Yet of the children of Israel did Solomon make no one a servant. But perhaps the above were merely salaried employees? We must therefore say that the above is inferred from here (II Chr. 2, 16) And Solomon numbered all the gerim (proselytes) that were in the land of Israel, etc., and they were found to be one hundred and fifty thousand. And he made of them seventy thousand bearers of burdens, etc. And was then the decree against the Gibeonites issued by David? Behold! Moses issued the decree, as it is written (Deut. 29, 10) from the hewer of the wood, etc. Moses merely decreed it for that generation, but David decreed it for all generations. Again has not Joshua decreed concerning them? For it is written (Josh. 9, 27) And Joshua appointed them only that day hewers of the wood, etc. Joshua's decree was only for the period during which the Temple existed, but David's decree was issued for the period beyond the destruction of the Temple.
