Midrash sobre Ester 2:5

“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.

Another interpretation: Just as Jacob hid from his father for twenty-two years, so did Joseph hide from his father for twenty-two years. It is therefore stated (in Gen. 37:2): THESE ARE THE GENERATIONS OF JACOB: JOSEPH.¹¹So Rashi with considerable explanation on Gen. 37:34. R. Levi said: Rabbi Johanan said: Wherever it says, HE WAS, the HE saw three worlds.¹²Cf. Gen. R. 30:8; Esth. R. 6:3. It is written of Noah (in Gen. 6:9): HE WAS PERFECT. He saw the world when it was inhabited before the flood came, he saw it destroyed, and he saw it afterwards in its restoration. It is therefore said of him: HE WAS. In the case of Moses, it is written (in Exod. 3:1): HE WAS TENDING < THE FLOCK OF HIS FATHER-IN-LAW JETHRO, THE PRIEST OF MIDIAN >…. He saw Israel before the bondage tightened its grip, he saw the bondage, and {they} [he] saw them when they had been redeemed. [Of Mordecai it is written] (in Esth. 2:5): THERE WAS (literally: HE WAS) A CERTAIN JEW IN THE CITADEL OF SHUSHAN. He saw them (Israel) before they were enslaved at the hand of Haman, he saw them under the edicts which had been decreed against them, and he saw them in their redemption. Of Job it is written (in Job 1:1): THERE WAS (literally: HE WAS) A MAN IN THE LAND OF < UZ >, and he saw three worlds. He was whole, he suffered afflictions, and he was healed. So also in the case of Joseph, HE WAS is written of him (in Gen. 37:2): THESE ARE THE GENERATIONS OF JACOB: JOSEPH AT THE AGE OF SEVENTEEN WAS (literally: HE WAS) TENDING < THE FLOCK WITH HIS BROTHERS >….

“The young woman who will please the king will reign in place of Vashti. The proposal pleased the king and he did so” (Esther 2:4).
“The young woman who will please the king” – who is fitting for this thing? ¹⁵Fit to raise the woman who would be chosen as queen. Mordekhai – “there was a Jewish man in the Shushan citadel, and his name was Mordekhai” (Esther 2:5).¹⁶This is the immediately following verse. This and the subsequent passages are all cases where the midrash addresses the juxtaposition of two verses. It asks about the first verse: who is fitting for this thing? It then finds the answer in the next verse.
Similarly, “God saw the children of Israel and God knew” (Exodus 2:25). Who is fitting for this matter? Moses – “And Moses was herding” (Exodus 3:1).
Similarly, “Samuel said to the men of Israel: Go, each man to his city” (I Samuel 8:22). Who is fitting for this thing [to be appointed king]? Saul, as it is stated: “There was a man of Benjamin, and his name was Kish…[and he had a son and his name was Saul…]” (I Samuel 9:1–2).
Similarly, “Saul and all Israel heard these words of the Philistine, and they were dismayed and were greatly afraid.” (I Samuel 17:11). Who is fitting for this thing [fighting Goliath]? David – “David was the son of that Efrati [from Bethlehem]” (I Samuel 17:12).
Rabbi Yehoshua bar Aviram said two things. It is written: “He [Yavin king of Canaan] oppressed the children of Israel strongly [beḥozka] for twenty years” (Judges 4:3). What is beḥozka? Rabbi Yitzḥak said: With cursing and blaspheming. That is what is written: “Your words have been harsh against Me” (Malachi 3:13). Who is fitting for this thing? Deborah, as it is written: “Deborah was a prophetess, wife of Lapidot” (Judges 4:4).
Rabbi Yehoshua bar Aviram said another: “The people, the princes of Gilad, said one to another: Who is the man who will begin to wage war against the children of Amon? He will be the head of all the inhabitants of Gilad” (Judges 10:18). Who is fitting for this thing? Yiftaḥ – “Yiftaḥ the Giladite was a mighty warrior” (Judges 11:1).
