Midrash sobre Daniel 1:4

“He said: Bring the kerchief that is upon you, and hold it, and she held it. He measured six measures of barley, and placed it on her; and he came to the city” (Ruth 3:15).
“He said: Bring [havi (fem.)] the kerchief that is upon you,” – hava [masc.] is written,²²⁴In the standard version of the book of Ruth, this term is actually written havi, not hava. teaching that he spoke to her in masculine language so no one would sense.²²⁵That a woman was present. “And hold it,” teaching that she girded her loins like a man.²²⁶She was very powerful in her ability to carry so great a burden. “He measured six measures of barley, and placed it on her.” ²²⁷The literal translation is “six barleys” rather than six measures of barley. Rabbi Simon said: Bar Kappara expounded in Tzippori: Is it the way of a king²²⁸Boaz, who was a judge. to marry a woman with six grains of barley? Or is it the way of a woman to carry six se’a? Rabbi Yehuda bar Rabbi Simon said: By virtue of “he measured [vayamod] six barleys and he placed them on her,” she was privileged, and six righteous men emerged from her, and each one of them had six attributes [middot]: David, Hezekiah, Josiah, Ḥananya, Mishael, Azarya,²²⁹Ḥananya, Mishael, and Azarya are counted here as one, because they acted together and displayed the same characteristics (Matnot Kehuna). Daniel, and the messianic king.
David, as it is stated: “Skillful in playing, a mighty man of valor, a man of war, understands matters, a comely person, and the Lord is with him” (I Samuel 16:18). Hezekiah, as it is stated: “For abundant authority and boundless peace on the throne [of David]” (Isaiah 9:6). “He called his name: Wonder, adviser, leader, mighty, eternal father, prince of peace” (Isaiah 9:5). Some say: “For abundant authority [lemarbe hamisra]…,” lemarbe is written without a mem.”²³⁰Actually, it is written with a closed mem, usually found at the end of the word; an allusion to the fact that Hezekiah was disqualified from being the messianic king because he failed to sing God’s praises (Sanhedrin 94a). Josiah, as it is stated: “For he will be like a tree planted by the water, that spreads its roots near the river, [does not see when heat comes, its foliage will be fresh; and will not be anxious in a year of drought, and will not cease from producing fruit]” (Jeremiah 17:8). Ḥananya, Mishael, and Azarya, as it is stated: “Youths in whom there was no blemish, fair in appearance, [skillful in all wisdom, knowledgeable and understanding in thought, with ability to stand in the king's palace, and for him to teach them the writings and the language of the Chaldeans]” (Daniel 1:4). Daniel, as it is stated: “Since surpassing spirit, [knowledge, understanding, interpreting of dreams, declaring of riddles, and solving of problems were found in Daniel]” (Daniel 5:12). The messianic king, as it is stated: “The spirit of the Lord will rest upon him, the spirit of wisdom [and understanding, the spirit of counsel and might, the spirit of knowledge and of the fear of the Lord]” (Isaiah 11:2).

R. Tanchum said: "Bar Kappara lectured in Sepphoria: "What does the passage (Ruth, 3, 17) These six barleys gave he unto me mean? How are six barleys to be understood? Shall we take it literally. Ib. b) Would a man like Boaz give six grains of barley as a gift? Shall we assume that it means measures of barley. How can a woman carry six measures? Therefore the six barleys were a prediction that in the future six sons would come out of her, each of them would be blessed with six blessings: viz., David, Messiah, Daniel, Chananyah, Mishael, and Azaryah. David — as it is written (I Sam. 16, 18) Then answered one of the servants, and said, Behold, I have seen a son of Jesse the Betlechemite, who is skilled as a player and a mighty valiant man, and a man of war, and intenigent in speech and a person of good form, and the Lord is with him. And R. Juda said in the name of Rab: "The whole verse was said by Doeg the Edomite, with the intention of slander, i.e., who is skilled as a player — who knows how to ask questions; a mighty valiant man, who knows how to answer questions; a man of war — who understands argument in the disputations of the Torah; intelligent in speech — he understandeth how to derive one thing from another (argument by analogy); a person of good form — who is able to give good reasons for Halakhas; the Lord is with him — the Halakha always prevails with him. To all the things mentioned above Saul said: "My son Jonathan possesses all the same qualities." But when he heard that the Halakha prevailed with him, a qualification which he himself did not possess, he felt discouraged and began to be jealous, for concerning Saul it is written (I Sam 14, 47) And whithersoever he turned himself, he caused terror, and about David it is written: In whatsoever he turned to he was successful. But whence do we know that it was Doeg who said so? From the following passage (Ib. 16, 18) One of the servants — the most distinguished of them; and (Ib. 26, 8) And his name was Doeg the Edomite, the chief of the herdsman that belonged to Saul. Messiah — as it is written (Is. 11, 2) And there shall rest upon him the spirit of the Lord, the spirit of wisdom and understanding, the spirit of counsel and might; the spirit of knowledge and of the fear of the Lord. Daniel,Chananyah, Mischael and Azaryah — as it is written (Dan. 1, 4) Lads in whom there should be no kind of blemish, but who should be handsome in appearance, and intelligent in counsel and might; the spirit of knowledge and undersatnd science, and such as should have the ability to serve in the king's palace, and that these should be taught the learning and the language of the Chaldeans. And it is also written Vaharikho (animated). R. Alexandri said: "Infer from this that he is always overloaded with the divine commandments and chastisements resting upon him as Rechayim (a handmill)." Raba said: "He judges by smelling," as it is written further, And not after the sight of the eyes shall he judge, and not after the hearing of ears… . [nevertheless] he judges with righteousness the poor and decides with equity for the suffering ones of the earth, and he shall smite the earth with the rod of his mouth, and with the breath of his lips shall he slay the wicked. [Hence, if not by the eye and not by the ear, it must be by smelling.] Therefore when [Bar Kokhba] said to the sages: "I am Messiah," they answered him concerning Messiah: "It is written He judges by smelling; let us see if he does also judge by smelling." As soon as they saw that he did not judge by smelling, they executed him. And now cocerning the verse cited about Chananyah, Mishael, etc., 'they had no blemish.' R. Chama b. Chanina said: "Not even a scratch, caused by the piercing of the lancet, was to be found on their bodies." The ability to serve in the king's palace, i.e., they were able to restrain themselves from laughing, sleeping and dreaming, and even from departing for one's necessity for fear of the king.
