Exodus 11:9

And Yahweh said to Moses, “When you go to return to Egypt, see to it that all the miraculous wonders which I have put in your hand, that you do them before Pharaoh; but as for Me, I will harden his heart with strength so that he will not let the people go.

“But I will harden Pharaoh’s heart with stiffness that I may multiply My signs and My wonders in the land of Egypt.

“But Pharaoh will not listen to you. And I will set My hand upon Egypt and bring out My hosts, My people the sons of Israel, from the land of Egypt by great judgments.

“Then You performed signs and wonders against Pharaoh, Against all his servants and all the people of his land; For You knew that they acted presumptuously toward them, And made a name for Yourself as it is this day.
