Midrash sobre Salmos 27:1

How important He is to us, David tells us in the verse: The Lord is my light and my salvation; whom shall I fear? (Ps. 27:1). When did David utter this verse? While fighting against the Amalekite bands. He fought against them at night and slew them, as it is said: And David smote them from the twilight even unto the evening (I Sam. 30:17). Who indeed lit the shooting stars and sent the lightning for them? R. Eleazar the son of Pedat was of the opinion that this verse refers to the war waged against the Egyptians after they pursued the Israelites. Observe what is written there: And there was the cloud and the darkness here, yet it gave light by night there (Exod. 14:20). R. Oshaya declared: When the Israelites saw the light they cried out: The Lord is my light and my salvation; whom shall I fear? The Holy One, blessed be He, said to Israel: If you light lamps before Me, I will illumine the world in your behalf with a great light, as it is said: But the Lord shall be unto thee an everlasting light, and thy God thy glory (Isa. 16:19).

It is taught: Until a person sins, he is given terror and fear and creatures are afraid of him. Once he sins, terror and fear are imposed upon him and he is afraid of others. Know that it is so, as Rabbi said: Until Adam the first man sinned, he would hear the voice of divine speech while standing on his feet and was not afraid. Once he sinned, when he heard the voice of divine speech, he was afraid and hid, as it is stated: “I heard your voice…” (Genesis 3:10); “the man hid” (Genesis 3:8). Rabbi Aivu said: At that moment the height of Adam’s stature diminished and it became only one hundred cubits. Rabbi Levi said: Until Adam the first man sinned, he would hear a soothing divine voice. Once he sinned, he would hear a thundering voice.
Until Israel sinned, they would see⁹⁰They would see the glory of God. through the consecutive partitions and they were not afraid, shocked, and frightened. Once they sinned, they could not have even looked at an intermediary. That is what is written: “They saw the skin of Moses’s face, that it was radiant” (Exodus 34:35), and it is written: “They feared to approach him” (Exodus 34:30).
Rabbi Pinḥas and Rabbi Avun said in the name of Rabbi Ḥanin: Even the intermediary was affected with them in that transgression. Until Israel sinned, what is written? “The kings of armies flee again and again” (Psalms 68:13). Rabbi Aivu said: “Angels [malakhei] of armies” is not written, but rather “kings [malkhei] of armies”—the kings of the angels. Which is they? They are Mikhael and Gavriel. They were unable to look at Moses’s face. Once [the Israelites] sinned, [Moses] was unable to look even at the most ordinary among [the angels]. That is what is written: “For I was in dread of the wrath and the fury” (Deuteronomy 9:19).
Until that incident befell David,⁹¹The reference is to David’s sin with Batsheva. See II Samuel chap. 11. it is written: “The Lord is my light and my salvation; whom shall I fear?” (Psalms 27:1). Once it befell him, it is written: “I will come upon him, and he will be weary and discouraged” (II Samuel 17:2). Until Solomon sinned, he would subjugate sharim and sharot.⁹²The meaning of these words is unclear. Perhaps it may be read sarim and sarot, in which case it means princes and princesses. Alternatively, some suggest that the text should read shedim veshedot, male and female demons. That is the text found in a parallel midrash in Yalkut Shimoni Tehillim 795. That is what is written: “I acquired for myself male and female singers [sharim vesharot]” (Ecclesiastes 2:8), male singers [meshorerim] and female singers [meshorerot];⁹³In this phrase, the midrash has merely translated the terms used in the verse to more familiar forms of the words. “and the pleasures of people” (Ecclesiastes 2:8), bathhouses; “chests [shida] and wagons [shidot]” (Ecclesiastes 2:8), male and female demons [sheda veshedta] who would heat them. Once he sinned, he appointed for him “sixty valiant men…from the valiant of Israel” and positioned them to protect his bed. That is what is written: “Behold the bed…each armed with a sword,” because he was afraid of the spirits.

... Teach us, oh master – may one light a lamp for personal use from the Channukah lights? Our masters taught us – R’ Acha said in the name of Rav ‘it is forbidden to light a lamp to use from the Channukah lights, but one may light a Channukah light from a Channukah light.’ From where did they learn that it is permissible to light a Channukah light (from it)? R’ Yaakov ben Aba said, they learned it from the menorah that was in the Holy of Holies, as our rabbis taught that if one found they had gone out, they should be cleaned out and re-lit from those that are still lit. (Tamid 3) If we would relight an extinguished lamp of the menorah, which was placed in the innermost sanctum, from the lamps still burning all the more so it is permissible to light a Channukah light from the lights still burning.’ The Holy One said, just as in this world lamps were lit in the Holy of Holies, so too I will do when I rebuild Jerusalem. From where do we know this? From the words of the prophet “And it shall come to pass on that day, that I will search Jerusalem with candles…” (Tzephaniah 1:12)

Hananiah the son of Hakinai and Rabbi Shimon the son of Yohai went to study Torah with Rabbi Akiva in Bnei Brak. They were there for 13 years. Rabbi Shimon the son of Yohai used to send letters to his wife, and used to know what was happening to his family. Hananiah the son of Hakinai did not send letters to his wife and did not know what was happening to his family. His wife sent to him, "Your daughter is grown; come and find her a match." [He wished to enter his house but found that it was turned in a different direction.] What did he do? He went and sat by the well. He heard the voices of the water-drawers saying, "Daughter of Hakinai, fill your pitcher and ascend." She went, and he went after her, until he came into his house. Just as his wife saw him, her soul left her. {There are those who say that it returned}

...Another explanation. 'The LORD is my light and my help...' My light by the sea, as it says "...and it lit up the night..." (Exodus 14:20) And my help by the sea, as it says "...Stand by, and witness the deliverance which the LORD will work for you..." (ibid. v. 13) Whom should I fear? "But Moses said to the people, “Have no fear!" (ibid.) The LORD is the stronghold of my life, "The LORD is my strength and might..." (Exodus 15:2) Whom should I dread? "Terror and dread descend upon them..." (ibid. v. 16) When evil men assail me, "As Pharaoh drew near..." (Exodus 14:10) To devour my flesh, "...My desire shall have its fill of them..." (Exodus 15:9) R' Shmuel bar Nachmani said: the wicked do not leave this world until they announce their own verdict upon themselves. This is what is written "I will pursue, I will overtake" (ibid.) It does not then say 'we will divide' but rather "I will divide the spoil" (ibid.) I will be divided. It is they, my foes and my enemies, who stumble and fall, "Who hurled Pharaoh and his army into the Sea of Reeds..." (Psalms 136:15) From here forward Israel said 'Should an army besiege me...' meaning the army of Egypt, '...my heart would have no fear.' 'should war beset me, because of this would I be confident.' 'This' always refers to Torah, as it says "This is the Teaching..." (Deuteronomy 4:44) The rabbis explained this verse as referring to Rosh HaShanah and Yom Kippur. 'my light,' on Rosh Hashanah. 'And my help ,' on Yom Kippur. 'When evil men assail me,' this refers to the idolaters. 'To devour my flesh,' when they come to accuse Israel and say before the Holy One: these (meaning themselves) are idolaters and those (meaning Israel) are idolaters as well! 'my foes and my enemies,' the numerical value of the letters of hasatan (the accuser) is 364. Every day of the year he has the authority to make accusations, except on Yom Kippur (and Rosh Hashanah). For this reason Israel said 'Should an army besiege me,' meaning the idolatrous nations, 'my heart would have no fear.' 'Should war beset me, because of this would I be confident,' R' Levi said: because of the bequest which you wrote in the Torah "Thus only shall Aaron enter the Shrine..." (Vayikra 16:3)
