Midrash sa 1 Samuel 1:1: Ein Yaakov (Glick Edition), Vayikra Rabbah, Ruth Rabbah & Esther Rabbah

(Fol. 10, b) And it came to pass in the days of Ahasuerus. R. Levi, and according to others, R. Jochanan, said: "There is a tradition among us from our ancestors [who reicev it from] the men of the Great Assembly, that wherever Vayehi (it came to pass) occurs, it refers to some disaster. (Ruth 1) And it came to pass in the days of Ahasuerus, there was Haman; (Jud. 1) And it came to pass in the days of the Judges, there was hunger; (Gen. 6, 1) And it came to pass when men began to multiply, and soon after this it is written, And the children of man, etc. — [which caused the flood]; (Ib. 11, 2) And it came to pass as they journeyed toward the east, then there came the dispersion; (Ib. 14, 1) And it came to pass in the days of Amraphel … there was a war. (Josh. 5, 13) It came to pass when Joshua was by Jericho, etc. and he saw a man with a drawn sword in his hand; (Ib. 6, 27) And the Lord was (Va'yehi) with Joshua, and soon after this. And the children of Israel committed a trespass; (I Samuel) There was (Va'yehi) a certain man of Romathaim, and afterward, Hannah he loved, but the Lord had shut her womb; (Ib. 8, 1) It came to pass when Samuel became old … and his sons walked not in his way; (Ib. 18, 14) And David was successful all his ways, and soon follows, Saul was in dread of him; (II Sam. 7, 1) And it came to pass when the king dwelt in his house. But thou canst not build the Temple. But is it not written (Lev. 9, 1) And it came to pass on the eighth day, and we have been taught in a Baraitha: "That particular day caused as great rejoicing before the Holy One, praised be He! as did the day of creation, for it is written here. And it came to pass (Va'yehi) on the eighth day, and it is written (Gen. 1, 5) And it was (Vayehi) evening and it was morning the first day. [Hence we find Vayehi when a misfortune does not follow.] There also the tragedy of Nadab and Abihu happened (Lev. 10, 1-7). But is it not written (I Kings 6, 1) And it came to pass in the four hundred and eightieth year after the going forth of the children of Israel out of Egypt, and it is also Written (Gen, 29, 16) While Jacob saw Rachel, and in Genesis (1, 5) And it was evening, and it was morning, the first day — and so on the second and third days although no disaster occurred? We must therefore say that wherever it is said, (Vayehi) It came to pass, there may or may not be a calamity; but whenever it is said, (Vayehi Bimai), And it came to pass in the days of, there a misfortune surely took place. There are five expressions, It came to pass in the days of, viz., in the days of Ahasuerus, the Judges, Amraphel, Ahaz (Is. 7) and Yehoyakim (Jer. 1) [and in every instance there was trouble] .

“Ephraim…to Me” – Rabbi Yehoshua ben Levi said: A palace dweller.⁸In the view of Rabbi Yehoshua ben Levi, Ephraim derives from the term apiryon meaning the seat of kings. Rabbi Yehoshua bar Naḥman said: Of noble descent.⁹In the view of Rabbi Yehoshua bar Naḥman, Ephraim derives from the term peri meaning a scion, in this case, of nobility. Rabbi Pinḥas said: Ephraim was granted this crown by Jacob our patriarch when he passed to his eternal abode. He said to him: ‘Ephraim, tribal leaders, yeshiva heads, and the finest and most outstanding of my descendants will be called by your name.’ “[Elkana, son of Yeroḥam, son of Elihu,] son of Toḥu, son of Tzuf, a nobleman [efrati]” (I Samuel 1:1); “David was the son of that nobleman [efrati] from Bethlehem of Judah” (I Samuel 17:12).
“Is Ephraim a precious son to Me, a child of delights?” (Jeremiah 31:20). What is a child of delights? One who is two or three years old. Rabbi Aḥa in the name of Rabbi Levi ben Sisi: One who is four or five years old.
“For whenever I speak of him [midei daberi bo]” (Jeremiah 31:20) – Rabbi Yudan in the name of Rabbi Abba bar Kahana: My speech [diburi] that I have placed in him is sufficient [dai].¹⁰The Torah that I have given to them is sufficient for Me to think fondly of them. Rabbi Yehuda ben Rabbi Simon said: Even when I speak of him, I cannot bear it,¹¹This is due to My extreme love for him. “for whenever I speak of him,” for of course I speak of him.

“The name of the man was Elimelekh, and the name of his wife Naomi, and the names of his two sons Maḥlon and Kilyon, Ephratites of Bethlehem in Judah. They came to the fields of Moav, and were there” (Ruth 1:2).
“The name of the man was Elimelekh” (Ruth 1:2). Rabbi Meir would expound names. Rabbi Yehoshua ben Korḥa would expound names. “The name of the man was Elimelekh,” as he would say: To me [elai], the kingdom [malkhut] will come. “And the name of his wife was Naomi,” as her actions were fine [na’im], and pleasant [ne’imim]. “And the names of his two sons Maḥlon and Kilyon” – Maḥlon, for they were eradicated [nimḥu] from the world; Kilyon, for they were eliminated [kalu] from the world. “Ephratites,”⁸³An expression of greatness. Rabbi Yehoshua ben Levi says: He was a resident of the palace. Rabbi bar Rabbi Neḥemya says: He was a nobleman. Another matter, “Ephratites,” Rabbi Pinḥas said: The entire crown with which Ephraim was crowned by Jacob at the moment that he passed from the world. He said to him: ‘Ephraim, tribal heads, heads of the yeshiva; the most excellent and outstanding of my children will be called by your name.’ “Son of Toḥu, son of Tzuf, Ephratite” (I Samuel 1:1);⁸⁴This verse is referring to Elkana. Ephratite means from Ephraim. “Yorovam ben Nevat Ephratite” (I Kings 11:26); David, son of an Ephratite man” (I Samuel 17:12); “Maḥlon and Kilyon, Ephratites.”
