It is a remarkable moment. After eight plagues, the ones who crack first are not Pharaoh — but his own courtiers.
"The servants of Pharoh said, How long shall this man be a stumbling-block to us? Let the men be released, that they may worship before the Lord their God. Art thou not aware that by His hand it will be that the land of Mizraim shall be destroyed?" (Targum Pseudo-Jonathan on Exodus 10:7).
The Aramaic paraphrase, preserved in the Targum attributed to Yonatan ben Uzziel, puts the question in blunt court-language. Ad emati yehei gavra hadein lan l'takla — how long will this man be a stumbling-block to us? The servants call Moses this man, gavra. They are still trying to reduce him. But their question betrays them: they have begun to see him as the hinge on which Egypt's fate turns.
And then the piercing line: Art thou not aware that by His hand the land of Mizraim shall be destroyed? These are not prophets. These are advisors, staff officers, career men who have served Pharaoh for years. And they are telling him to his face: you are going to lose everything.
The Maggid teaches: when a leader's own inner circle starts contradicting him publicly, it means the walls of his denial have cracked so wide that even the people paid to agree can no longer pretend. Pharaoh ignores them. That is how far gone he is.
