Мидраш к Эстер 2:7

The great Rabbi Hoshaya opened [with the verse (Mishlei 8:30),] "I [the Torah] was an amon to Him and I was a plaything to Him every day." Amon means "pedagogue" (i.e. nanny). Amon means "covered." Amon means "hidden." And there is one who says amon means "great." Amon means "nanny," as in (Bamidbar 11:12) “As a nanny (omein) carries the suckling child." Amon means "covered," as in (Eichah 4:5) "Those who were covered (emunim) in scarlet have embraced refuse heaps." Amon means "hidden," as in (Esther 2:7) "He hid away (omein) Hadassah." Amon means "great," as in (Nahum 3:8) "Are you better than No-amon [which dwells in the rivers]?" which the Targum renders as, "Are you better than Alexandria the Great (amon), which dwells between the rivers?" Alternatively, amon means "artisan." The Torah is saying, "I was the artisan's tool of Hashem." In the way of the world, a king of flesh and blood who builds a castle does not do so from his own knowledge, but rather from the knowledge of an architect, and the architect does not build it from his own knowledge, but rather he has scrolls and books in order to know how to make rooms and doorways. So too Hashem gazed into the Torah and created the world. Similarly the Torah says, "Through the reishis Hashem created [the heavens and the earth]," and reishis means Torah, as in "Hashem made me [the Torah] the beginning (reishis) of His way" (Mishlei 8:22).

R. Jonathan would begin [his Purim lecture] with this passage (Ib. 14, 22) I will cause to rise up against them, etc., And I will cut from Babylon name and remnant, and son and grandson, saith the Lord; i.e.. Name, refers to the art of writings; remnant, refers to their language; and son, refers to the kingdom; grandson, refers to Vashti. R. Samuel b. Nachmeni [when he came to lecture] would begin with the passage (Is. 55, 13) Instead of the thorn shall come up the cypress, and instead of the brier shall come up the myrtle; i.e., instead of the thorn, instead of Haman the wicked, who made himself an idol, as it is written (Ib. 7, 19) And upon all thorns. Shall come up the cypress (Brosh); i.e., Mordecai, who was the essence of all the spices, as it is said (Ex. 30, 23) And thou, take unto thyself the chief (Rosh) spices, of flowing myrrh; this is translated in the Targum Onkeles Mordecai; and instead of the brier, i.e., Vashti the wicked, the grand-daughter of Nebuchadnezzar, the wicked, who had burnt the house of God, concerning whom it is written (Son. 3, 10) Its cover-lid is gold; shall come up the Hadassa (myrtle), referring to Esther the upright, who was called Hadassa, as it is said (Esther 2, 7) And he had brought up Hadassah, that is Esther; and it is also written (Zech. 1, 8) And he was standing among the myrtle-trees; (Ib.) And it shall be unto the Lord for a name, refers to the days of Purim; (Ib.) For a sign of everlasting that shall not cut off, refers to the reading of the Megilla."

“We have become orphans, fatherless; our mothers are like widows” (Lamentations 5:3).
“We have become orphans, fatherless.” Rabbi Berekhya said in the name of Rabbi Levi: The Holy One blessed be He said to Israel: ‘You wept and said before Me: “We have become orphans, fatherless.” As you live, the redeemer that I am destined to establish for you in Media will not have a father and mother.’ That is what is written: “He was raising Hadasa, she is Esther his uncle’s daughter, because she had no father or mother” (Esther 2:7).
