Exodus 9:33-35

International Standard Version

³³ Then Moses went out of the city from Pharaoh and spread out his hands to the Lord. The thunder and hail stopped, and the rain no longer poured out on the land. ³⁴ When Pharaoh saw that the rain, hail, and thunder had stopped, he continued to sin. He, along with his officials,^[a] hardened his heart. ³⁵ Pharaoh’s heart was stubborn,^[b] and he did not let the Israelis go, just as the Lord had said through Moses.
