מדרש אויף תהילים 93:3

Rabbi Levi said: The waters said to one another: ‘Let us go and fulfill the command of the Holy One blessed be He.’ That is what is written: “The rivers raise, Lord; the rivers raise their voices. [The rivers boost their towering waves [dokhyam]]” (Psalms 93:3). Rabbi Levi said: [They exclaimed:] ‘Via the sea [derekh yam], via the sea.’ Rabbi Abba bar Kahana said: ‘To such-and-such place [dukhta], to such-and-such corner, such-and-such waves.’ Rav Huna said: ‘To this sea [hadakh yama], to this sea.’ Rabbi Yehoshua bar Ḥanina said: ‘To water channels [dukhsa yam], to water channels.’
Rabbi Elazar said: The sea absorbed them, just as you say: “Have you entered into the depths of the sea?” (Job 38:16) – within the boundaries of the sea. The Rabbis say: [The waters exclaimed:] ‘We are pressed down [dokhim], receive us. We are broken [medukhanim], receive us.’
Rabbi Yehoshua ben Rabbi Neḥemya said: The water would ascend mountains and descend depths until it reached the ocean. That is what is written: “They rose to the mountains, descended [in the valleys to the place You established for them]” (Psalms 104:8). What place did You establish for them? This is the ocean.
Rabbi Abahu expounded: The ocean is higher than the entire world, and the whole world in its entirety drinks from its water.

"Even the world was not stable, Rabbi Abbahu said a parable: What is this matter like? It is like a king who first conquered a certain province. The leader of the province gave the king a cornerstone that did not move from its place. Similarly, when the Holy One, blessed be He, created His world, the earth shook and said, 'I am not stable.' The Holy One, blessed be He, said to it, 'I will give you a cornerstone,' as it is written, 'He founded the earth upon its bases; it shall not falter forever and ever.' (Psalms 104:5) True is Your throne from the beginning. This is one of seven things that were created before the world was created, and they are: the Throne of Glory, as it is written, 'True is Your throne from the beginning,' the name of the King Messiah, as it is written, 'Before the sun, his name is Yinnon,' (Psalms 72:17) and why is he called Yinnon? Because he will ennoble those who are downtrodden like a dove that is crushed and turns to dust. The Torah, as it is written, 'The Lord acquired me as the beginning of His way' (Proverbs 8:22), Israel, as it is written, 'Remember Your congregation which You acquired long ago' (Psalms 74:2), the Temple, as it is written, 'A throne of glory, exalted from the beginning, is the place of our sanctuary' (Jeremiah 17:12), repentance, as it is written, 'Before the mountains were born, before You brought forth the earth and the inhabited world, from eternity to eternity You are God' (Psalms 90:2), and Gehenna, as it is written, 'For from yesterday it was prepared' (Isaiah 30:33). Rabbi Shimon ben Lakish said: When the Philistines returned the Ark, they began to boast and say, 'It was not only the Ark that was between us and our Lord, but also His Master.' This is what is written, 'The rivers raise, O Lord' (Psalms 93:3). And what are the rivers? They are none other than the Philistines, as it is written, 'From the river is the land of the Philistines' (1 Samuel 5:6). The Holy One, blessed be He, said, 'The rivers will raise themselves with haughtiness, but I will break them with hard afflictions.' 'With haughtiness.' Rabbi Samuel bar Nachmani said: Their internal affairs are corrupt. 'I will break them.' Rabbi Shimon ben Lakish said: Their external affairs are corrupt. 'The rivers will raise, O Lord.'"

Another thing the rivers of God lifted up. Rabbi Berechiah said in the name of Ben Azai that the waters were rising and reaching up to the throne of glory, as it is said, "And the spirit of God was hovering over the face of the waters" (Genesis 1:2). And it also says, "As an eagle awakens its nest, hovering over its young" (Deuteronomy 32:11). And when the bee emerges from the mouth of the Almighty (Genesis 9:10), the waters would gather together. Mountains and hills rose up from the ends of the earth and spread throughout the land, creating valleys upon valleys in the midst of the earth, and the waters would roll and gather into the valleys, as it is said, "And he called the gathering of the waters 'Seas'" (Genesis 1:10). Immediately, the waters swelled and covered the land, until God rebuked them and pressed them beneath His feet, forming a border for the sea as a man makes a fence around his vineyard. And when the waters rose and saw the sand before them, they receded, as it is said, "Fear not, O Jacob My servant," says the Lord, "for I am with you; for I will make a complete end of all the nations where I have driven you, but I will not make a complete end of you. I will rightly correct you, for I will not leave you wholly unpunished" (Jeremiah 46:28). And before the waters were gathered together, the deeps were created. These are the depths that are beneath the earth, and the earth above them is split like a crack in a vessel, gazing into the heart of the sea. Thus, the earth is anchored upon the waters, as it is said, "Who laid the foundations of the earth, that it should not be removed forever" (Psalm 104:5). And where did those waters go? Rabbi Berechiah said in the name of Rabbi Yudan and Rabbi Yehudah, the son of Rabbi Shalom: "What is this thing like? It is like two bowls, one full and one empty. But if they were both full, what could they do? When they are full, they pour into the channel, and when the wind passes through them, they turn to one place. So the whole world was filled with water. What did the Holy One, blessed be He, do? He restrained them, and they dried up, as it is said, 'He holds back the waters, and they dry up; also, he sends them out, and they overturn the earth' (Job 12:15). And it also says, 'He walks on the high places of the sea' (Job 9:8), "He holds back the waters, and they dry up." And it also says (Micah 1:3), "He treads upon the high places of the sea." And it says (Psalm 33:7), "He gathers the waters of the sea together as a heap." And where did they go? Rabbi Levi said, "These whisper to these, 'Where are we going?' And they say, 'The way of the sea, the way of the sea, to make war with that country, to make war with that country.'" Rabbi Huna drew out a tongue of fire to each side. Rabbi Joshua ben Karcha said, "We have received that the voice of the Holy One, blessed be He, was roaring before them, as it is said (Psalm 29:3), 'The voice of the Lord is upon the waters.' The rivers raise their voice."
