What we can learn from 3 Torah couples
Yitzchok and Rivka
(21) Yitzchok pleaded with the LORD on behalf of his wife, because she was barren; and the LORD responded to his plea, and his wife Rivka conceived.
(1) ויהי אחרי מות אברהם ויברך וגו AND IT CAME TO PASS AFTER THE DEATH OF AVRAHAM THAT GOD BLESSED YITZCHOK etc. — He comforted him with the words of the formula of consolation which we offer to mourners (Sotah 14a). Another explanation is: Although the Holy One, blessed be He, had entrusted the blessings to Avraham to bless whomever he wished yet he (Avraham) feared to bless Yitzchok, because he foresaw that Esav would be born from him. He therefore said, “Let the Master of the blessings come himself and bless whomever it seems proper in his eyes” — God came and blessed him (Yitzchok)(Genesis Rabbah 61:6).
The Midrash says:
"Opposite his wife." This teaches us that Yitzchok prostrated himself [in prayer] here and Rivka here, saying: "Master of the universe, all the children that You are to give me, may they be from this righteous woman." She also said the same thing: "All children that You are to give me in the future, may they be from this righteous man."
Yaakov and Rachel
(1) When Rachel saw that she had borne Yaakov no children, she became envious of her sister; and Rachel said to Yaakov, “Give me children, or I shall die.” (2) Jacob was incensed at Rachel, and said, “Can I take the place of God, who has denied you fruit of the womb?”
The Midrash says:
After hearing how Yaakov expressed himself to his wife, Hashem said, "Is this how you respond to those in distress?"
Chana and Elkanah
(6) Moreover, her rival, to make her miserable, would taunt her that the LORD had closed her womb. (7) This happened year after year: Every time she went up to the House of the LORD, the other would taunt her, so that she wept and would not eat. (8) Her husband Elkanah said to her, “Chana, why are you crying and why aren’t you eating? Why are you so sad? Am I not more devoted to you than ten sons?”
(9) After they had eaten and drunk at Shiloh, Chana rose.—The priest Eli was sitting on the seat near the doorpost of the temple of the LORD.— (10) In her wretchedness, she prayed to the LORD, weeping all the while. (11) And she made this vow: “O LORD of Hosts, if You will look upon the suffering of Your maidservant and will remember me and not forget Your maidservant, and if You will grant Your maidservant a male child, I will dedicate him to the LORD for all the days of his life; and no razor shall ever touch his head.”
(12) As she kept on praying before the LORD, Eli watched her mouth. (13) Now Chana was praying in her heart; only her lips moved, but her voice could not be heard. So Eli thought she was drunk. (14) Eli said to her, “How long will you make a drunken spectacle of yourself? Sober up!” (15) And Chana replied, “Oh no, my lord! I am a very unhappy woman. I have drunk no wine or other strong drink, but I have been pouring out my heart to the LORD. (16) Do not take your maidservant for a worthless woman; I have only been speaking all this time out of my great anguish and distress.”
Moshe and the Luchos
(1) The LORD said to Moshe: “Carve two tablets of stone like the first, and I will inscribe upon the tablets the words that were on the first tablets, which you shattered.
§ Rabbi Ḥama, son of Rabbi Ḥanina, said: Moshe became wealthy only from the waste remaining from hewing the Tablets of the Covenant, as it is stated: “Hew for you two tablets of stone like the first” (Exodus 34:1). “Hew for you” means that their waste shall be yours. As the tablets were crafted from valuable gems, their remnants were similarly valuable.
