Midrasch zu Mischlej 17:19

Son of man, say unto the prince of Tyre: Thus saith the Lord God: Because thy heart is lifted up, and thou hast said: I am a god, I sit in the seat of God, in the heart of the seas; yet thou art man, and not God (Ezek. 28:2). Scripture states elsewhere in allusion to this verse: Be not rash with thy mouth, and let not thy heart be hasty to utter a word before God; for God is in the heavens and thou art upon the earth; therefore, let thy words be few (Eccles. 5:1). It says also: He loveth transgression that loveth strife, he that lifteth his gate seeketh destruction (Prov. 17:19). Should this verse not state that “he who lowereth his gate²⁷Thereby placing temptation before others. seeketh destruction,” since everyone who lowers his gate causes people to stumble and to be destroyed: What then is the meaning of he that lifteth his gate seeketh destruction? This means that one who opens his mouth and utters words that are unseemly brings on his own destruction, for the Holy One, blessed be He, will destroy him. Therefore, it is said: Be not rash with thy mouth (Eccles. 5:1).

“The king’s scribes were summoned on the thirteenth day of the first month, and it was written in accordance with everything that Haman had commanded the king’s satraps, and the governors who were over every province, and the princes of every people; to every province in its script, and to every people in its language. It was written in the name of King Aḥashverosh, and it was sealed with the king's ring” (Esther 3:12).
“The king’s scribes were summoned...and it was written in accordance with everything that Haman had commanded.” It is written: “Pharaoh commanded all his people, saying: Every son who is born, you shall cast him into the Nile…” (Exodus 1:22). Pharaoh commanded, but the Holy One blessed be He did not command. You [Haman], what power do you have? “Who is this, who said and it occurred, if the Lord did not command?” (Lamentations 3:37). What did He command? “For with a powerful hand he will send them out” (Exodus 6:1); and so it happened to him. Moreover, “He tossed Pharaoh and his army in the Red Sea” (Psalms 136:15).
Similarly, “in accordance with everything that Haman had commanded” – he commanded, but the Holy One blessed be He did not command. Haman commanded “to destroy, to kill and to eliminate” (3:13), but the Lord did not command. What did He command? “May his evil plot that he had devised against the Jews return upon his head” (Esther 9:25), and so it happened to him, “and they hanged him and his sons on the gibbet” (Ibid.).
It is written: “He who elevates his entrance seeks destruction” (Proverbs 17:19). One who elevates the pronouncements of his mouth and utters inappropriate matters from his mouth, the Holy One blessed be He breaks him, and in the pot in which he cooked, he is cooked. Likewise, with Yitro it says: “As it was in the matter that they conspired against them” (Exodus 18:11).
