Midrash sobre I Samuel 8:2

“Naomi had an acquaintance of her husband’s, a mighty man of valor, from the family of Elimelekh, and his name was Boaz” (Ruth 2:1).
“Naomi had an acquaintance [moda] of her husband’s, a mighty man of valor” – moda means relative. Rabbi Abbahu said: If a giant marries a giantess, what do they produce? Mighty men of valor. Boaz married Ruth; what did they produce? David, “who knows how to play, a mighty man of valor, a man of war, understanding in matters, a comely man, and the Lord is with him” (I Samuel 16:18). “Who knows how to play” – [refers to his expertise] in Bible; “a mighty man of valor” – in Mishna; “a man of war” – he knows to negotiate the battle of Torah; “understanding in matters” – in good deeds; “a comely man” – in Talmud. Alternatively: “Understanding in matters” – he infers one matter from another matter; “a comely man” – who displays understanding in halakha; “and the Lord is with him” – the halakha is in accordance with his opinion.
“From the family of Elimelekh, and his name was Boaz” – the wicked precede their name: “Goliath was his name” (I Samuel 17:4); “Naval is his name” (I Samuel 25:25); “Sheva son of Bikhri was his name” (II Samuel 20:21). However, the righteous, their names precede them: “And his name was Kish” (I Samuel 9:1); “and his name was Saul” (I Samuel 9:2); “and his name was Yishai” (I Samuel 17:12); “and his name was Mordekhai” (Esther 2:5); “and his name was Elkana” (I Samuel 1:1). It is because they are similar to their Creator, as it is written: “But with My name, the Lord, I was not known to them” (Exodus 6:3).
They objected to him: “And his name was Laban” (Genesis 24:29). Rabbi Yitzḥak said: This is an obvious characteristic.¹⁴⁹He was extremely white [lavan] or was a senior judge who sought to clarify matters. Laban was not his real name. Rabbi Berekhya said: He was blatant [meluban] in his wickedness. But is it not written: The sons of Samuel, “the name of the firstborn was Yoel and the name of his second, Aviya” (I Samuel 8:2), [and] the Rabbis say: Just as this one was wicked, so too, that one was wicked? Rabbi Yehuda ben Rabbi Simon said: Because they changed their actions and merited the Divine Spirit, as it is stated: “The word of the Lord that was to Joel [Yoel] son of Petuel” (Joel 1:1).¹⁵⁰The midrash interprets Petuel as a reference to Samuel; see Bemidbar Rabba 10:5.

... “He does the will of those who fear Him…” (Tehillim 145:19) Meaning that Gd does not annul his prayers and gives him what he requests. This refers to David, of whom it is written “I am a companion to all who fear You…” (Tehillim 119:63) at the time when he was troubled over the Holy Temple, as it is written “Remember, O Lord, onto David all his affliction. That he swore to the Lord, he vowed to the Mighty One of Jacob; That I shall not come into the tent of my house, and I shall not go up on the bed that was spread for me. I shall not give sleep to my eyes nor slumber to my pupils, Until I find a place for the Lord, dwellings for the Mighty One of Jacob.” (Tehillim 132:1-5) Since the Holy One saw that he stood there, troubled over the Holy Temple, He immediately sent Gad the prophet to him and showed him the place of the Holy Temple, as it is written “And Gad came to David on that day, and said to him, ‘Go up to erect an altar to the Lord in the threshing-floor of Aravnah the Jebusite.’” (Shmuel II 24:18) David went there immediately, as it says “And David went up according to the word of Gad, as the Lord had commanded. (Shmuel II 24:19) He found there the altar where Adam, the first man, made offerings, where Noach made offerings, where Avraham made offerings. Once he found it he began to measure, saying ‘from here to here will be the Courtyard, from here to here will be the Holy of Holies’ as it says “And David said, ‘This is the House of the Lord God…” (Divre HaYamim I 22:1) And how could he declare “…and this is the altar for burnt offerings for Israel” (ibid.)? This is what is meant that the Holy One does not nullify the desire of the righteous, but rather gives them what they seek in order to fulfill “He does the will of those who fear Him…” (Tehillim 145:19)
