Midrasch zu Divrej Hajamim I 2:18

(Ex. 1, 21) And it came to pass because the midwives feared God that He made them houses. Rab and Levi both explain the above passage: One says that this means kingly houses and the other said it means priestly and Levite houses. The latter interpretation refers to Moses, and the former contends that kings came forth from Miriam who was also one of the midwives, for it is written (I Chr. 1, 2) And Azubah died when Kaleb took unto himself Ephroth who bore unto him Chur and again it is written (I Sam. 17, 22) Now David was the son of that Ephritite, [hence David was of the same family as Miriam]. (I Chr. 2, 18) And Kaleb the son of Chetzron begot children of Azubah, and of Jerioth and these were her sonss Jeshner, Shobah and Ardon. Is he then the son of Chetzron? Behold he is the son of Yephunah, as stated (Num. 13, 6) He was called with the last name because he turned away from the advice of the spies. And again is he not the son of Kenaz, as it is written (Hosh. 15, 17) And Othniel, the son of Kenaz, the brother of Kaleb, captured it? Said Raba: "He was a step-son to Kenaz." (Fol. 12) This can be proved by the following — he is called a Kenizzite, but not the son of Kenaz. Hence the inference is maintained. (Ib. 14, 14) Azubah, refers to Miriam, "why was she called Azubah? Because every young man forsook her in the beginning; she begot, behold, she was married to him and she begot him? Said R. Jochanan: "Whoever marries a man from a respectable family for heavenly sake is considered by Scripture as if he begot her." Yerioth she was called, because her face was greenish like the curtains of the Temple. And these were her sons. Do not read Baneha (her sons) but boneha {who built her up); yashar means who kept himself straight in the right path, [did not listen to the spies]; Sho'ab means, who turned himself away [from his evil inclinations]; Ardon means who rebelled against his evil inclination, and according to others because his face was as prim as a rose. (I Chr. 4, 5) And Aschuhr the father of Teke'ah had two wives, Chelba and Nea'arah; i.e., Ashchur refers to Kaleb, and why was he called Ashchur; because he darkened his face because of the many fasts he observed, Abi, who became like a father to his wife; teko'ah, who attached his heart unto his Father in heaven; there were two wives, the one Miriam became like two wives; Chela and Na'arah, neither was her name Chela nor Na'arah, but it means in the beginning she was sick, and at the end she became young, (Ib., ib. 7) And the sons of Chilah were Zareth, Zochar and Ethnan; i.e., Zureth means that she caused grief and animosity to her friend [because of her beautiful] appearance; Zochar means that her face was like the mid-day; Ethnan because she appeared very handsome.

(Gen. 29:31:) WHEN THE LORD SAW THAT LEAH WAS HATED. This text is related (to Ps. 145:14): THE LORD UPHOLDS ALL WHO FALL AND RAISES UP ALL WHO ARE BOWED DOWN. {It is not said < in the text > "All who stand upright," but ALL WHO ARE BOWED DOWN. And does he also raise up the wicked?} R. Hiyya said: The behavior of the Holy One is not like the behavior of one who is flesh-and-blood. According to flesh-and-blood behavior, < if > one has a wealthy friend, he clings to him and pines for him; but, as soon as his power (literally: hand) declines and he becomes poor, he laughs at him. With the Holy One, however, things are not like that. As soon as he sees someone whose power is down, he gives him a hand and raises him up. Thus it is stated (ibid.): THE LORD UPHOLDS ALL WHO FALL. It is not said < in the text > "All who stand," but ALL WHO FALL. (Ibid., cont.:) AND RAISES UP ALL WHO ARE BOWED DOWN. Would you say that he also raises up the wicked, if they come to a fall? No, for it is stated (in Ps. 36:13 [12]): THERE THE EVILDOERS HAVE FALLEN; THEY ARE THRUST DOWN AND CANNOT RISE. They have fallen; there is no standing for them. Why? Because it is stated (in Ps. 35:5): < THEY SHALL BE > LIKE CHAFF BEFORE THE WIND WITH THE ANGEL OF THE LORD OVERTHROWING THEM. But those who are righteous (according to Ps. 145:14): THE LORD UPHOLDS. As soon as the Holy One saw that Leah was hated, he said: How am I to make her dear to her husband? Just look, I am raising her up and giving her children first so that she will become loved by her husband. Therefore (according to Gen. 29:31): WHEN THE LORD SAW THAT LEAH WAS HATED. Now it also says (in I Chron. 2:18): AND CALEB BEN HEZRON HAD CHILDREN BY AZUBAH, A WIFE, AND BY JERIOTH; AND THESE WERE HER SONS: JESHER, SHOBAB, AND ARDON. R. Berekhyah said: She was his wife.³²The biblical text actually states that Azubah and Jerioth were Caleb’s daughters, but Exod. R. 1:17 explains in the name of R. Johanan, “that in the case of anyone who takes a wife for the sake of heaven above (i.e., for no reason beyond producing children), he is recorded as having given birth to her.” Then why was she called Azubah? Because she was abandoned (azubah) and ugly. The Holy One said: Look, I am giving her children so that she will become beautiful through them. Thus it is stated (ibid.): AND THESE WERE HER SONS: JESHER, SHOBAB, AND ARDON. It is therefore stated (in Ps. 145:14): THE LORD UPHOLDS ALL WHO FALL AND RAISES UP ALL WHO ARE BOWED DOWN.
