Midras Yesaya 45:15: Otzar Midrashim, Mekhilta DeRabbi Yishmael, Shir HaShirim Rabbah & Pirkei DeRabbi Eliezer

Blessed be the name of the King of kings, the Holy One blessed be He, who lives and endures forever and ever. As it says "But as I live" (Numbers 14:21) and "The Lord God is truth" (Jeremiah 10:10). He sees births and knows what will happen in the future, as it says "Declaring the end from the beginning" (Isaiah 46:10). And no one can oppose Him, as it says "There is no one who can stay His hand" (Daniel 4:32).

And it says "Where the word of a king rules" (Ecclesiastes 8:4) - God is unsearchable... He hides and conceals Himself from the sight of all living, as it says "Surely You are a God who hides Himself" (Isaiah 45:15) and it says "He sits enthroned out of sight" (Isaiah 6:1). Yet everything is revealed before Him, as it says "He reveals deep and hidden things" (Daniel 2:22).

"and I will be honored through Pharaoh": Scripture here apprises us that when the L–rd exacts punishment of the nations, His name is aggrandized in the world, as it is written (Isaiah 66:19) "And I will put a sign upon them (the nations), and I will send some of them as survivors to the nations — Tarshish, Pul, Lud, the Archers, Toval and Yavan … and they will declare My glory among the nations," and (Ibid. 45:14-15) "Thus said the L–rd: The toil of Egypt and the men of Cush and the Sabeans, men of stature, will pass to you and will become yours. They will follow after you and pass in chains. They will prostrate themselves before you. They will pray before you — Only with you is G–d, and there is none other except for G–d." What follows? "You are a G–d who conceals Himself. The G–d of Israel is the Savior." And it is written (Ezekiel 38:22) "And I will punish him (Gog) with pestilence and with blood, torrential rain and hailstones, fire and sulphur, etc.", followed by (23) "And I will be exalted and I will be sanctified, and I will make Myself known before the eyes of many nations, and they will know that I am the L–rd." And it is written (Psalms 76:3) "And His tabernacle will be in Jerusalem, and His dwelling in Zion, etc." And (Ibid. 4) "There He broke the flying bows, shield, sword, and battle, Selah." (Ibid. 2) "G–d is known in Judah. His name is great in Israel."
