Exodus 9:33-10:2

New International Version

³³ Then Moses left Pharaoh and went out of the city. He spread out his hands toward the Lord; the thunder and hail stopped, and the rain no longer poured down on the land. ³⁴ When Pharaoh saw that the rain and hail and thunder had stopped, he sinned again: He and his officials hardened their hearts. ³⁵ So Pharaoh’s heart^(A) was hard and he would not let the Israelites go, just as the Lord had said through Moses.

10 Then the Lord said to Moses, “Go to Pharaoh, for I have hardened his heart^(B) and the hearts of his officials so that I may perform these signs^(C) of mine among them ² that you may tell your children^(D) and grandchildren how I dealt harshly^(E) with the Egyptians and how I performed my signs among them, and that you may know that I am the Lord.”^(F)
