Complete Jewish Bible

⁸ All your servants will come down to me, prostrate themselves before me and say, “Get out! — you and all the people who follow you!” and after that, I will go out!’ ” And he went out from Pharaoh in the heat of anger. ⁹ Adonai said to Moshe, “Pharaoh will not listen to you, so that still more of my wonders will be shown in the land of Egypt.”

¹⁰ Moshe and Aharon did all these wonders before Pharaoh, but Adonai had made Pharaoh hardhearted, and he didn’t let the people of Isra’el leave his land.
