Exodus 11:8

וירדו כל עבדיך AND ALL THY SERVENTS SHALL COME DOWN [UNTO ME] — He showed respect to the king, for as a matter of fact ultimately Pharaoh himself came down to him at night, (Exodus 12:31) “And he said, Arise, go out from the midst of my people”; but Moses did not at the outset say to him, “And thou shalt come down to me and shalt prostrate thyself”, out of respect for the king, (Exodus Rabbah 7:3) אשר ברגליך (lit., who are at thy feet) — who go after (follow) thy counsel and ways. ואחרי כן אצא AND AFTER THAT I WILL GO OUT, with all my people, from thy land. ויצא מעם פרעה AND HE WENT OUT FROM PHARAOH — After he had concluded his words he went forth from his presence. בחרי אף IN FIERCENESS OF WRATH because he (Pharaoh) had said to him, (Exodus 10:28) “Do not again see my face.

וְיָרְד֣וּ כׇל־עֲבָדֶ֩יךָ֩ אֵ֨לֶּה אֵלַ֜י וְהִשְׁתַּֽחֲווּ־לִ֣י לֵאמֹ֗ר צֵ֤א אַתָּה֙ וְכׇל־הָעָ֣ם אֲשֶׁר־בְּרַגְלֶ֔יךָ וְאַחֲרֵי־כֵ֖ן אֵצֵ֑א וַיֵּצֵ֥א מֵֽעִם־פַּרְעֹ֖ה בׇּחֳרִי־אָֽף׃ {ס}        

And all these thy servants shall come down to me, and bow down themselves to me, saying, Get thee gone, and all the people that follow thee: and after that I will go out. And he went out from Par῾o in great anger.
