וַיּ֨וֹשַׁע יְהוָ֜ה בַּיּ֥וֹם הַה֛וּא אֶת־יִשְׂרָאֵ֖ל מִיַּ֣ד מִצְרָ֑יִם וַיַּ֤רְא יִשְׂרָאֵל֙ אֶת־מִצְרַ֔יִם מֵ֖ת עַל־שְׂפַ֥ת הַיָּֽם׃
그 날에 여호와께서 이같이 이스라엘을 애굽 사람의 손에서 구원하시매 이스라엘이 바닷가의 애굽 사람의 시체를 보았더라
Otzar Midrashim
"Midrash Vayosha": This is a midrash on the Song of the Sea and the Exodus from Egypt. It is named after the verse "And the Lord saved Israel that day" (Exodus 14:30), and it seems that the midrash primarily began with this verse, including the legend of Uzza, the angelic prince of Egypt, and his dispute with Michael, the angelic prince of Israel, before the Divine Throne concerning the duration of the enslavement. After this, the story of the Binding of Isaac was added to its beginning, even though it doesn't truly belong there. Midrash Vayosha is cited in the book "Bachayei" on Parsha Beshalach, which states: "According to the midrash, 'And behold, the Egyptians were marching after them.' The prince of Egypt saw that there was an angel descending from the heavens to help Egypt, and he was Uzza. I also saw in the Midrash Vayosha that Uzza was the prince of Egypt." This is also cited in the book "Minchat Shai" by Rabbi Raphael Manortzi on Parsha Beshalach.

“Each at his banner, with the insignias of their patrilineal houses, the children of Israel shall encamp; at a distance, around the Tent of Meeting, they shall encamp” (Numbers 2:2).
“Each at his banner…,” that is what is written: “We will sing with joy at your salvation and raise banners in the name of our God…” (Psalms 20:6). Israel said before the Holy One blessed be He: ‘We are singing with joy at Your salvation, what You have done on our behalf in Your name’ – “we will sing with joy at Your salvation.” “The Lord saved [vayosha] Israel on that day” (Exodus 14:30). Vayivasha is written,1The letters of vayosha (saved somebody else) are the same as the letters of vayivasha (was himself saved). as it were, Israel is saved and it is as though He was saved. “And raise banners in the name of our God,” as the Holy One blessed be He affixed His name to ours and arranged us according to banners, as it is stated: “Each at his banner.”

Mekhilta DeRabbi Yishmael
(Exodus 14:30) "and the L–rd saved Israel on that day": As a bird held in a man's hand, so that if he pressed its hand but a little he would choke it, as it is written (Psalms 124:6-8) "Our soul (at the splitting of the sea) escaped as from the hunter's snare. The snare broke and we escaped. Our help is in the name of the L–rd, Maker of heaven and earth." Or: As a man releasing a fetus from a cow's womb, as it is written (Devarim 4:34) "Or has a G–d ever done miracles to come and take for Himself a nation from the midst of a nation, etc."? Why "a nation from the midst of a nation"? — As a man releasing a fetus from a cow's womb, viz. (Ibid. 20) "and you did the L–rd take, and He brought you forth from the iron furnace, etc."
