מדרש אויף ישעיהו 57:20

R. Chisda said in the name of Mar Ukba: "Every man who possesseth haughtiness, the Holy One, praised be He! says concerning him: 'I and he cannot live in the same world,' as it is said (Ib. 101, 5) Who slandereth in secret his neighbor, him will I destroy; Whoso is proud of eye, and haughty of heart, him could I not bear." Do not read Otho [him], but read Itho [with him.] But others, however, explain the above passage to refer to tale-bearers, as it is said. Whoso slandereth in secret his neighhor. R. Alexanderi said: "Whoever possesses haughtiness, even in the slightest degree, it shall cause his downfall, as it is said (Is. 57, 20) But the wicked are like the troubled sea; jar it can never be at rest. If the sea, which contains so many quarts of water, is nevertheless stirred up by the slightest breeze, how much more so should slight assumption affect a man in whom there is only one quart of blood?" R. Chiya b. Ashi said in the name of Rab: "A scholar should possess one-eighth of an eighth (one-sixty-fourth) of pride." R. Huna, the son of R. Joshua, said: "This befits a scholar like the ears of the standing crop grain." Raba said: "Under ban should be anyone who possesses it on a great scale; under ban, and again under ban, should be the one who does not possess it at all." R. Isaac, however, said: "Neither the whole nor a bit should one possess, for how can we consider so light the warning, (Pr. 16, 5) An abomination of the Lord is everyone that is proud of heart."

“Why do nations rumble” (Psalms 2:1) – this [relates to] that which is said by Scripture, “But the wicked are like the rumbling sea [which cannot rest, whose rumbling waters [raise up] mire and mud]” (Isaiah 57:20). Just as the sea [vomits] all of its refuse upon its mouth [i.e., upon the sea shore], so does the refuse of the wicked [come to rest] upon their mouths. Pharoah said, “Who is God [that I should heed him and let Israel go?]” (Exodus 5:2). Sisera “oppressed the Children of Israel, harshly [for twenty years]” (Judges 4:3). What [does scripture refer to when it says that the oppression was] harsh? [It means] that [in addition to any physical oppression] he oppressed them [verbally] with blasphemy and insults. [And the fact that the word “harsh” can refer to speech is] like that which is written, “You have spoken harsh words against me” (Malachi 3:13). [Following the pattern of Pharoah and Sisera,] Sennacherib said, “Which among all of the gods of [those vanquished] countries [saved their country from my hand, such that God should save Jerusalem from my hand?]” (II Kings 18:35). [And] Nebuchadnezzar said, “what god is there that can deliver you from my hand?” (Daniel 3:15).

An alternative interpretation of: “Why do nations rumble” (Psalms 2:1) – this [relates to] that which is said by Scripture, “It is [God] who sits above the horizon of the earth [and its inhabitants are like grasshoppers]” (Isaiah 40:22). To what can the wicked be compared? They are like grasshoppers, placed in a jar, they struggle to escape, but they [keep] falling. This is what the wicked are like. Rabbi Yehuda bar Nachmani said, after the generation of the flood, it is written, “And all [the people of] the land spoke one language” (Genesis 11:1) – [thus beginning the story of Babel]. Couldn’t the later generation have learnt [its lesson] from the earlier generation? And [likewise] Gog and Magog will arise in the epoch to come, and they [too] will fall. And David saw [this] and said, “Why do nations rumble?” [i.e., why don’t they learn their lesson?] An alternative interpretation: just as the wave of the sea ascends and gets stronger, as if it will flood the world, but then, when it reaches the shore, it prostrates itself [literally: it flattens itself] before the sand; so too with the idolatrous nations; [and so too with] all who conspire against the Israelites, to harm them. [Ultimately, they will] fall before them. Why? Because Israel is compared to sand. As it is said, “The number of the people of Israel shall be like that of the sands of the sea,” (Hosea 2:1). And the idolatrous nations are compared to the sea. As it says, “But the wicked are like the rumbling sea” (Isaiah 57:20). One finds that Nimrod and his colleagues conspired against Abraham and [then] fell before him. As it is said, “At night, he and his servants deployed against them [and defeated them],” (Genesis 14:15). Abimelech [fell] before Isaac; Esau before Jacob; Pharoah and Egypt before Israel; and so too many more [such stories appear] in the Torah. And even in the time to come, Gog and Magog are destined to fall before Israel. And David saw this and wailed [in prayer, saying] “Why do nations rumble?” [i.e., God, why do you allow the nations to pursue such folly?] Rabbi Yitzchak said, even if a person asks his friend, “Why are you acting like this?”, his friend will be angry with him. But the righteous say to the Holy One, blessed be He, “Why are you acting like this?”, and they are not punished. And why are they not punished? Because they were not asking for their own benefit, but for [the benefit] of Israel. Rabbi Aybo said, all of the tumult and toil of the wicked is for nothing. As it is said, “Peoples shall toil to no end” (Jeremiah 51:58). But Israel “shall not toil to no end; they shall not bear children [destined] to misfortune” (Isaiah 65:23).
