Exodus 7:13

“And you shall take in your hand this staff, with which you shall do the signs.”

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 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 Yahweh said to Moses, “Come to Pharaoh, for I have hardened his heart and the heart of his servants with firmness, that I may set these signs of Mine among them,

and His signs and His works which He did in the midst of Egypt to Pharaoh the king of Egypt and to all his land;

“Why then do you harden your hearts as the Egyptians and Pharaoh hardened their hearts? When He had abused them, did they not allow the people to go, and they went?

“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.
