מדרש אויף בראשית 16:2

Who perceiveth that her merchandise is good (Prov. 31:18). That was when the kings attacked them, as it is written: And he divided himself against them by night (Gen. 14:15). She stretcheth out her hand to the poor (Prov. 31:19), by giving food to passers-by. Yea, she reacheth forth her hand to the needy (ibid., v. 20); for she gave charity and clothed the naked. She is not afraid of the snow for her household (ibid., v. 21); that is, she did not fear Gehenna. And why not? Because her entire household possessed garments (shanim, punning on shnayim, “two”) (ibid.): Sabbath and circumcision. She maketh for herself coverlets (ibid., v. 22): These were the priestly garments. From the fruit of her hand she planted a vineyard (ibid., v. 16). This refers to Israel, as it is said: For a vineyard of the Lord of hosts is the house of Israel (Isa. 5:7). Her husband is known in the gates (Prov. 31:23); that is, when he pleaded with the sons of Seth: Give me a possession of a burial place (Gen. 23:4). She maketh linen garments (Prov. 31:24) refers to the circumcision that took place, as it is said: The counsel of the Lord is with them that fear Him (Ps. 25:14). Strength and dignity are her clothing (Prov. 31:25) alludes to the clouds of glory that encircled her tent. She openeth her mouth with wisdom (ibid. 39:26). When was that? When she said to Abraham: Go, I pray thee, unto thy handmaid (Gen. 16:2). She looketh well to the ways of her household (Prov. 31:27) indicates that she watched every day for the return of the angel who had informed her: I will certainly return unto thee (Gen. 18:10).

The Holy One blessed be He said: ‘Heed Me, as there is no person who heeds Me and loses.’ The Rabbis say: You find there is one who heeds [his wife and loses, and one who heeds] his wife and gains. How so? Adam the first man heeded his wife and lost. From where is this derived? As it is stated: “And to Adam He said: Because you heeded the voice of your wife…[cursed is the ground on your account]” (Genesis 3:17). Rabbi Yitzḥak said: To what is the matter comparable? To a king who said to his servant: ‘Do not taste anything until I return from the bathhouse.’ His wife said to him: ‘Taste the cooked dish, so he will not need to seek to add salt or fish gravy.’ The king came and saw him licking his lips. The king said to him: ‘Did I not tell you do not eat, and yet you ate?’ He said to him: ‘My master, your maidservant gave it to me.’ The king said to him: ‘And you heeded my maidservant more than me?’ So, the Holy One blessed be He said to Adam: “But of the tree of the knowledge of good and evil, you shall not eat of it” (Genesis 2:17). What did Eve do? She fed him. Rabbi Avin said: She did not ask, but she wept and wailed to him with her voice, and he ate of it, as so it is written: “[Because you heeded] the voice of your wife.” “The words of your wife” is not written here, but rather, “the voice of your wife.” The Holy One blessed be He said to him: “Did you eat from the tree that I commanded you not to eat of it?” (Genesis 3:11). He said to Him: ‘My Master, Your maidservant gave it to me.’ From where is this derived? As it is stated: “The man said: The woman whom You gave to be with me, she gave me from the tree, and I ate” (Genesis 3:12). He said to him: ‘And you heeded Eve more than Me?’ [Adam] was immediately expelled [from the Garden of Eden], as it is stated: “He banished the man; He stationed the cherubs east of the Garden of Eden, and the blade of the ever-turning sword, to guard the path of the tree of life” (Genesis 3:24). That is, he heeded his wife and lost.
There is one who heeded his wife and gained. This is Abraham. From where is this derived? As it is stated: “Sarai said to Abram: Please, behold, the Lord has kept me from bearing; please, consort with my maidservant; perhaps I shall be built through her. Abram heeded the voice of Sarai” (Genesis 16:2). Rabbi Shmuel bar Naḥman said: To what is the matter comparable? To one to whom a son was born. A certain astrologer saw him and said: ‘This lad is destined to be an arch-robber, his father must cast him away.’ His father heard and said: ‘Would I cast away my son?’ The father of that astrologer heard and said: ‘Everything that my son said to you, heed him.’ So, Sarah foresaw that Ishmael was taking to evil ways, and she would say to Abraham: “Banish this maidservant and her son” (Genesis 21:10) and it distressed him. The Holy One blessed be He appeared to [Abraham] and said to him: “Do not be distressed about the lad and about your maidservant; everything that Sarah says to you, heed her voice…” (Genesis 21:12). He heeded her voice and gained, as his descendants were considered [only those] descending from Isaac, as it is stated: “For it is through Isaac that descendants will be accounted to you” (Genesis 21:12). The Holy One blessed be He said: ‘If one who heeded his wife is so rewarded, one who heeds Me, all the more so.’ King Solomon came and articulated it: “But one who heeds me will reside securely and tranquilly, without fear of evil” (Proverbs 1:33).

Observe that anyone who causes his neighbor to grieve is the first to be punished. Conversely Sarah was rewarded because she brought grief to herself when she said to Abraham: Behold now, the Lord hath restrained me from bearing; go in, I pray thee, unto my handmaid (Gen. 16:2). The Holy One, blessed be He, told her: Inasmuch as you inflicted distress upon yourself, you may be assured that with the very words you spoke, I will remember you. You said: The Lord hath restrained me; therefore it is written: The Lord hath restrained the wombs of the house of Abimelech (Gen. 20:18). The Holy One, blessed be He, declared: Abraham pleaded with Me in behalf of the wicked Abimelech, until I became merciful toward him; therefore, I shall remember Abraham together with him, as it is said: And God healed Abimelech, and his wife, and his handmaids (ibid., v. 17). What is written next? And the Lord remembered Sarah.
