Midrash su Abdia 1:8

“Its gates sank into the ground; He eradicated and broke its bars. Its king and its princes are among the nations; there is no Torah; its prophets, too, could not find a vision from the Lord” (Lamentations 2:9).
“Its gates sank into the ground,” Rabbi Huna said in the name of Rabbi Yosei: Gates accorded honor to the Ark; therefore, the enemy did not take control of them. That is what is written: “Lift your heads, gates, [and be lifted up, everlasting doors, that the King of glory may come in]” (Psalms 24:7).¹⁰⁴The Gemara (Shabbat 30a) relates that when Solomon sought to bring the Ark into the Temple, the gates would not open until he recited this verse. That is why “its gates sank into the ground; He eradicated and broke its bars.”
“Its king and its princes are among the nations; there is no Torah.” If a person will say to you: ‘There is wisdom among the nations,’ believe it. That is what is written: “I will eliminate the wise from Edom, and understanding from the mountain of Esau” (Obadiah 1:8). [If a person will say:] ‘There is Torah among the nations,’ do not believe it, as it is written: “Its king and its princes are among the nations; there is no Torah.”
“Its prophets,” these are the false prophets. “Its prophets, too,” these are the true prophets.¹⁰⁵The extraneous word “too” indicates that even the real prophets were no longer granted prophecy. These and those “could not find a vision from the Lord.”

R. Yehoshua of Sakhnin in the name of R. Levi, "They would interpret it, but their voices would not enter his ears. 'The seven good cows are seven daughters that you will beget, and the seven bad cows are seven daughters that you will bury.' Likewise they said, 'The seven good sheaves are seven kingdoms that you will conquer, and the seven bad sheaves are seven ministers that will rebel against you'"... Another interpretation: "And he sent and called" - to inform you that each and every nation that stands in the world is granted five wise men to serve it. Moreover, the Holy One, blessed be He, gives it three things: wisdom , understanding and strength. As so did the evil Sannacherib say (Isaiah 10:13), "By the might of my hand have I done this, etc." But when the Holy One, blessed be He, judges the world, He takes them away from it, as it is stated (Obadiah 1:8-9), "I will make the wise vanish from Edom, understanding from Esau’s mount.Your warriors shall lose heart, O Teman." And why so much? So that Joseph will come at the end and attain greatness. The Holy One, blessed be He, said, "If Joseph comes first and interprets the dream, this [will not earn] him praise. The magicians will be able to say to him, 'If you had asked us, we would have already interpreted it for you [the same way].'" Rather, [Joseph] waited for them until they tired him out and extracted his spirit. And afterwards Joseph came and brought it back [to him]. About this did Solomon say (Proverbs 29:11), "The fool extracts his entire spirit" - these are the wise men of Egypt; "but the wise man lowers it back" - this is Joseph, as it is stated (Genesis 41:39), "there is no one wise and understanding like you."
