Midrash su Salmi 35:2

Rabbi Papis expounded: “To a mare [lesusati] in Pharaoh's chariots”—lesisati is written.²⁴³The word lesusati is written without a vav such that it can also be read lesisati. The Holy One blessed be He said: ‘Just as I was gladdened [sasti] to eliminate the Egyptians at the sea, so I would have been gladdened to eliminate the enemies of Israel.’²⁴⁴The “enemies of Israel” is used here as a euphemism for the people of Israel themselves. Who caused them to be saved? “On their right and on their left” (Exodus 14:22); due to the merit of the Torah thay they were destined to receive from the right of the Holy One blessed be He, as it is stated: “From His right, a fiery law to them” (Deuteronomy 33:2). “And on their left,” this is mezuza.²⁴⁵The mezuza is situated to the left of the door when one is leaving the house. They were saved partially in the merit of their future fulfillment of the mitzva of mezuza. Alternatively, on their right, this is reciting Shema, “and on their left,” this is [the Amida] prayer.²⁴⁶Like the right, reciting Shema is superior because in it one does not request fulfillment of his own needs. By contrast, in the Amida prayer we request fulfillment of our own needs. This is exemplified in the verse: “Length of days is on its right; on its left is wealth and honor” (Proverbs 3:16) (Midrash HaMevoar). Rabbi Akiva said to him: ‘Enough, Papis. Every place that gladness [sisa] is stated, it is written with a sin, and here with a samekh.’ He said to [Rabbi Akiva]: ‘How do you interpret [the phrase] “to a mare in Pharaoh's chariots”?’ [Rabbi Akiva answered:] ‘Pharaoh mounted a stallion, and the Holy One blessed be He, as it were, revealed Himself on a stallion. That is what is written: “He mounted a cherub and flew” (Psalms 18:11). Pharaoh said: ‘A stallion kills its owners in war;²⁴⁷This is because its conduct is more aggressive. rather, I will ride on a mare.’ That is what is written: “To a mare in Pharaoh's chariots.” Pharaoh then rode on a red horse, on a white horse, or on a black one. As it were, the Holy One blessed be He revealed Himself on a red, white, and black horse. That is what is written: “You trampled in the sea with Your horses” (Habakkuk 3:15), interchanging horses.
The wicked Pharaoh emerged with armor and a helmet; as it were, the same is true of the Holy One blessed be He, as it is stated; “He donned righteousness like armor [and a helmet of salvation on His head]” (Isaiah 59:17). [Pharaoh] brought naphtha;²⁴⁸A flammable liquid, which he brought in order to use in battle. as it were, the same is true of the Holy One blessed be He, as it is stated: “Hail and coals of fire passed through His clouds” (Psalms 18:13). [Pharaoh] brought catapult stones; as it were, the same is true of the Holy One blessed be He, as it is stated: “And the Lord provided thunder and hail” (Exodus 9:23). [Pharaoh brought] swords and spears; as it were, the same is true of the Holy One blessed be He, as it is stated: “Many bolts of lightning” (Psalms 18:15). [Pharaoh] brought arrows; as it were, the same is true of the Holy One blessed be He, as it is stated: “He shot His arrows” (Psalms 18:15). Rabbi Levi said: “He shot his arrows and dispersed them” (Psalms 18:15) [teaches] that the arrows would scatter them; “many bolts of lightning and they confounded them” (Psalms 18:15) teaches that they would confuse them and confound them. He removed their banners²⁴⁹Without the banners, the formation of their camp disintegrated. and they did not know what they were doing.
Pharaoh emerged in full armor; as it were, the same is true of the Holy One blessed be He, as it is stated: “The Lord will emerge like a mighty man” (Isaiah 42:13). [Pharaoh] thundered with his voice; as it were, the same is true of the Holy One blessed be He, as it is stated: “The Lord would thunder from the heavens” (II Samuel 22:14). [Pharaoh] heartened them [his soldiers] with his voice; as it were, [the same is true of the Holy One blessed be He, as it is stated]: The Most High would project His voice” (II Samuel 22:14). Pharaoh emerged with fury; as it were, [the same is true of the Holy One blessed be He, as it is stated:] “With fury You trod the earth” (Habakkuk 3:12). [Pharaoh emerged] with a bow; as it were, [the same is true of the Holy One blessed be He, as it is stated:] “Your bow will be bared” (Habakkuk 3:9). [Pharaoh emerged] with shield and armor; as it were, [the same is true of the Holy One blessed be He, as it is stated:] “Grasp Your shield and armor” (Psalms 35:2). [Pharaoh emerged] with a flashing spear; as it were, [the same is true of the Holy One blessed be He, as it is stated:] “The glow of the flash of Your spear” (Habakkuk 3:11).
Rabbi Berekhya [said] in the name of Rabbi Shmuel bar Naḥman: When Paharaoh exhausted all his weapons, the Holy One blessed be He began exalting over him. He said to him: ‘Wicked one, do you have wind, do you have a cherub, do you have wings?’ From where did the Holy One blessed be He cause them to fly [to the sea]? Rabbi Yudan said: The Holy One blessed be He removed them from between the wheels of the Divine Chariot and flew them at the sea. Rabbi Ḥanina bar Pappa said: One who is flesh and blood rides upon something that carries him, and it is an item that has substance; however, the Holy One blessed be He is not so; He carries what He rides upon, and He rides upon an item that has no substance. That is what is written: “He mounted a cherub and flew, and He soared on wings of wind” (Psalms 18:11).
One verse says: “He soared [on wings of wind]” and one verse says: “He was seen on wings of wind” (II Samuel 22:11). In what sense can both verses be reconciled? Rabbi Aḥa said: From here [it may be derived] that the Holy One blessed be He has had many worlds and He emerges to be seen in them.
