Midrash su Salmi 30:2

... Teach us, our master, from when does the mitzvah of the Channukah lamp begin? Our rabbis taught – from when the sun sets until the majority of people are gone from the marketplace. And where are they to be lit? If one lives on an upper floor with a window facing the public domain, light there. If it is a time of danger, light within your house [and it is forbidden to do work by its light. R’ Asi said] it is forbidden to see by its light. Why do we light Channukah lamps? When the Hasmonean High Priest defeated the Greeks, as it says “For I bend Judah for Me like a bow; I filled [the hand of] Ephraim, and I will arouse your children, O Zion, upon your children, O Javan; and I will make you as the sword of a mighty man,” (Zechariah 9:13) they entered the Holy Temple. They found there eight iron stakes, fixed them in the ground and lit lamps upon them. Why do we read the Hallel psalms of praise? Because it is written “The Lord is God, and He gave us light.” (Tehillim 118:27) Why don’t we read it on Purim? It is written “…to destroy, to slay, and to cause to perish the entire host of every people and province that oppress them…” (Esther 8:11) and we don’t read it except to mark the fall of a kingdom and the kingdom of Ahasuerus still stood. But when the Holy One destroyed the kingdom of Greece they began to sing hymns and praises and to say that in the past we were servants to Pharoah, servants to Greece and now we are servants to the Holy One “Praise, you servants of the Lord…” (Tehillim 113:1) How many channukot (dedications) were there? There were seven. The dedication of heaven and earth, as it says “Now the heavens and the earth were completed…” (Bereshit 2:1) What dedication was there then? “And God placed them in the expanse of the heavens to shed light upon the earth.” (Bereshit 1:17) The dedication of the wall, as it says “And in the dedication of the wall of Jerusalem…” (Nechemiah 12:27) The dedication of those who came up from the exile, as it says “And they offered up for the dedication of this House of God…” (Ezra 6:17) The dedication of the priests, which we light for. The dedication of the world to come, as it says “And it shall come to pass on that day, that I will search Jerusalem with candles…” (Tzephaniah 1:12) The dedication of the princes “This was the dedication offering of the altar…” (Bamidbar 7:84) The dedication of the Sanctuary, which this is speaking of “A psalm; a song of dedication of the House, of David.” (Tehillim 30:1) Another explanation. There are seven channukot. The dedication of the creation of the world, as it is written “Now the heavens and the earth were completed…” (Bereshit 2:1) Completion is the language of dedication, as is written “All the work of the Mishkan of the Tent of Meeting was completed…” (Shemot 39:32) The dedication of Moshe, as it is written “And it was that on the day that Moses finished erecting the Mishkan…” (Bamidbar 7:1) The dedication of the House, as it is written “A psalm; a song of dedication of the House, of David.” (Tehillim 30:1) The dedication of the Second Temple [as it says “And they offered up for the dedication of this House of God…” (Ezra 6:17) and the dedication of the wall] as it says “And in the dedication of the wall of Jerusalem…” (Nechemiah 12:27) The current one of the House of Hasmonean. The dedication of the world to come, because even that has lights, as it is written “And the light of the moon shall be like the light of the sun, and the light of the sun shall be seven-fold as the light of the seven days…” (Isaiah 30:26)

(Ib. b.) Our Rabbis were taught: The orchestra of the thanks-offering consisted of violins, fifes, trumpets on every corner as well as on every elevated stone in Jerusalem and used to play (Ps. 30, 2) I will extol Thee, O Lord, for Thou hast lifted me, etc., and also (Ib. 91). Some call this later song Pegaim (destroyers) and some call this Negaim (plagues), because of the verse (Ib. 10) in which it reads, Nor shall any plague, etc.; others call it Pegaim, because of the verse (Ib. 1) There shall fall at thy side a thousand. They used to sing this song from verse one to ten inclusive, and also the whole of the third chapter of Psalms. R. Joshua b. Levi would say all the above mentioned verses before going to bed. How could he have done so. Has not R. Joshua b. Levi said that it is prohibited to cure one's self with [quoting] verses of the Torah? Protecting is different. Since he prohibited we must assume that it was in a case of a wound, if so then there is more than a prohibitory law; for we are taught that if one cures a wound by whispering, he has no share in the future world. Said R. Jochanan: "The latter refers to one who spits and then whispers, because the Heavenly name must not be mentioned on such an occasion." We are taught: One verse says (Num. 9, 13) He hath defiled the tabernacle of the Lord, and again it says further (20) Because he hath defiled the sanctuary of the Lord, etc. (Fol. 16b) R. Elazar says: Since the verse mentions the sanctuary, why should it mention the tabernacle, and if the verse mentions the tabernacle, why mention the sanctuary? The answer is: If only the tabernacle were mentioned, it could be accounted for by the fact that its being annointed with the holy oil, which was not the case with the temple, and therefore no liability is attached to defilement of the latter; on the other hand, if only the temple were mentioned, the reason might be given that it was sanctified once and forever, therefore the command which was not the case with the tabernacle; hence, the necessity of mentioning both the tabernacle and the sanctuary."

Another interpretation: “Haman took the garments and the horse....” (Esther 6:11). He came to Mordekhai and said: ‘Rise and get dressed.’ How unlucky is this man; last night I was engaged in arranging a gibbet for him, and the Holy one blessed be He arranged a crown for him. ‘I would have arranged for you ropes and nails, and the Holy one blessed be He arranged for you royal garments. I sought from the king to hang you on a gibbet, and he said to mount you on a horse. Stand up and get dressed.’ And he did everything we said above.
When he [Mordekhai] was riding, he began praising the Holy one blessed be He: “I will exalt You, O Lord, for You have lifted me up and have not caused my enemies to rejoice over me. O Lord my God, I cried out to You and You have healed me. O Lord, You brought my soul up from the grave; You have given me life that I not go down to a pit” (Psalms 30:2–4). What did his students say? “Sing to the Lord, his devout ones, and give thanks to His holy name. For His anger is a moment, life is by His will; in the evening one may lie down weeping, and in the morning, joy” (Psalms 30:5–6). What did that wicked one say? “And I said in my tranquility, I shall never be shaken. O Lord, by Your will You set my mountain strong – You hid Your face, I became terrified” (Psalms 30:7–8). What did Esther say? “To You, O Lord, I will call, and to the Lord I will make supplication. What profit is there in my blood, when I go down to destruction? Will dust thank You, will it declare Your truth?” (Psalms 30:9–10) What did the congregation of Israel say? “Hear O Lord and show favor to me; [O Lord, be my aid;] You have turned my lamenting into dance for me; [You have undone my sackcloth and girded me with joy]” (Psalms 30:11–12). What did the holy spirit say? “So that I can sing to You glorious praise, and not be silent, O Lord my God, forever I will thank You” (Psalms 30:13).
Haman’s daughter gazed from the window to see the hanging, and when she saw Mordekhai riding and her father declaring before him ‘so will be done for the man…,’ she cast herself to the ground and died.

R. Berechiah stated in the name of R. Helbo, who had said in the name of R. Samuel the son of Nahman: Most assuredly, the Holy One, blessed be He, judges the thoughts and the heart of man. Nebuchadnezzar praised Him in this verse just as David did in the Book of Psalms. Nebuchadnezzar said praise, and David said Praise the Lord, O Jerusalem (Ps. 147:12); Nebuchadnezzar said extol, and David said: I will extol thee, O Lord, for Thou hast raised me up (Ps. 30:2); Nebuchadnezzar said honor, and David declared: Thou art clothed with honor and majesty (ibid. 104:1). After he achieved greatness, however, he became arrogant, as it is said: Is not this great Babylon, which I have built for a royal dwelling-place, by the might of my power and for the glory of my majesty? (Dan. 4:27). Whereupon the Holy One, blessed be He, rebuked him: Wretch! Again you are boastful, as it is said: While the word was in the king’s mouth, there fell a voice from heaven: “O King Nebuchadnezzar, to thee it is spoken: The kingdom is departed from thee” (ibid., v. 28). Hence, whenever the wicked are in trouble, they humble themselves, but when their difficulties cease, they revert to their corrupt practices. Pharaoh did likewise. When he saw that the rain and the hail and the thunders were ceased, he continued to sin (Exod. 9:34). The gentiles add to their sins, but in the case of Israel The punishment of thine iniquity is accomplished, O daughter of Zion, he will no more carry thee away into captivity; He will punish thine iniquity, O daughter of Edom, he will uncover thy sins (Lam. 4:22).
