Midrasz do Rut 3:17

“She said: ‘These six measures of barley he gave me, as he said to me: Do not go empty-handed to your mother-in-law” (Ruth 3:17).
“She said: These six measures of barley he gave me…” Rabbi Alexandri said: Everywhere that Israel entered, they did not emerge empty-handed. In the looting of Egypt they did not emerge empty-handed, in the looting of Siḥon and Og they did not emerge empty-handed, in the looting of the thirty-one kings they did not emerge empty-handed. “Empty-handed” is stated regarding Egypt, as it is stated: “It will be when you depart, you will not depart empty-handed” (Exodus 3:21); [“empty-handed”] is stated regarding the festival pilgrims: “They shall not appear before Me empty-handed” (Exodus 23:15); and “empty-handed” is stated regarding the righteous, as it is stated: “As he said to me: Do not go empty-handed to your mother-in-law.” “Empty-handed” that is stated regarding the righteous is not like “empty-handed” that is stated regarding Egypt, but rather, like “empty-handed” that is stated regarding the festival pilgrims, as we learned there: The burnt offering of appearance [must be worth at least] two silver coins and the festival peace offering [must be worth at least] one silver ma’a (Mishna Ḥagiga 1:2).²³¹This is a relatively small amount, as the main point is to bring an offering of some kind. Similarly, what Boaz sent with Ruth to Naomi was not very expensive, but was an indication of honor and respect (Etz Yosef).

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.

X) For he said [to me], Do not go empty to your mother-in-law (Ruth 3:17) From the way this is written, we can learn that Ruth told Naomi her mother-in-law this matter two times — the first time she did not say to me,, but the second time she did say to me, so it was suspended on the margin.
