Midrash sa Mga Kawikaan 31:27: Midrash Tanchuma, Midrash Tanchuma Buber & Bereshit Rabbah

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).

(Gen. 19:24:) FROM THE LORD. What is written before the verse (in Gen. 19:1): THEN THE TWO ANGELS CAME TO SODOM IN THE EVENING.⁷⁴See Gen. R. 50:2. Elsewhere (in Gen. 18:2) three came to Abraham, as stated: WHEN HE RAISED HIS EYES, HE LOOKED, AND BEHOLD, THREE PERSONS. But here there are two, as stated (in Gen. 19:1): THEN THE TWO ANGELS CAME. It is simply that the Holy One sent three angels, each one individually to perform his < own particular > mission. One went to bring good tidings to Sarah, one went to save Lot, and one went to destroy Sodom. An angel does not perform two missions, [nor do two angels perform one mission]. Michael went to bring good tidings to Sarah. "Surely we will return unto you" is not written here (in Gen. 18:14), but I WILL RETURN. He performed his mission and went away. Then the < other > two went to perform their missions, as stated (in Gen. 19:1): THEN THE TWO ANGELS CAME TO SODOM IN THE EVENING. Elsewhere (in 18:2, 16, 19:5f.) < Scripture > has called them "persons," but here it has called them "angels." R. Alexandri, however, has said: < When angels were > near Abraham, they were < called > humans because angels were common in the house of Abraham.⁷⁵See Qid. 32b; cf. BM 86b. Thus it is stated (in Prov. 31:27): SHE OVERSEES THE ACTIVITIES (rt.: HLK) OF HER HOUSE. Since those who went (rt.: HLK) to the house of Abraham were angels and because he was commonly among angels, they appeared to him in human form.⁷⁶I.e., angelic visits were as common as household activities in Abraham’s house. But for Lot, who was ignorant⁷⁷Gk.: idotes, i.e., “lay person.” < about them >, they appeared as angels. Thus it is stated (in Gen. 19:1): THEN THE TWO ANGELS CAME TO SODOM….

“The angel of the Lord found her in the wilderness, at the spring of water on the road to Shur” (Genesis 16:7).
“The angel of the Lord found her…at the spring of water [on the road to Shur]…” – on the road to Ḥalutza.
“He said: Hagar, Sarai’s maidservant, from where did you come, and where are you going? She said: From my mistress Sarai I am fleeing” (Genesis 16:8).
“He said: Hagar, Sarai’s maidservant” – if one says to you: Your ears are like those of a donkey, pay him no mind; if two [people tell you this], make a bridle for yourself.³²If one person points out a fault to you, pay him no heed. If two people tell you, realize that the critique is true. So, Abram said: “Behold, your maidservant is in your hand.” The angel said: “Hagar, Sarai’s maidservant.” So she said: “From my mistress Sarai I am fleeing.”³³Both Abraham and the angel referred to her as a mere maidservant; as a result she regarded herself as a mere maidservant, by referring to Sarah as “my mistress.”
“The angel of the Lord said to her: Return to your mistress and suffer under her hands” (Genesis 16:9).
“The angel of the Lord said to her: I will multiply your descendants, and they shall not be counted due to their great number” (Genesis 16:10).
“The angel of the Lord said to her: Return to your mistress and suffer…The angel of the Lord said to her: I will multiply…” How many [different] angels encountered her? Rabbi Yosei bar Ḥanina said: Five – every time “saying” is stated, there was another angel.³⁴The words: “The angel of the Lord found her” is also counted as a “saying.” The Rabbis say: Four – every time “angel” is stated [there was another angel].
Rabbi Ḥiyya said: Come and see how great the difference is between the earlier generations and the later generations. Manoaḥ said to his wife [upon seeing an angel]: “We will die because we have seen God” (Judges 13:22). But Hagar, Sarai’s maidservant, saw five angels one after the other and did not fear them. Rabbi Ḥiyya said: [Better] the fingernail of the forefathers and not the belly of the descendants.³⁵The preceding generations are so much greater than their descendants that even the former’s fingernails are most substantial than the latter’s torso.
Rabbi Yitzḥak said: “She supervises [tzofiya] the proceedings of her household” (Proverbs 31:27)³⁶This verse is expounded as a reference to Abraham and Sarah in the Midrash of Proverbs. – the members of Abraham’s household were prophets [tzofim], so she was accustomed to seeing them [angels].
