English Standard Version
Chapter 9 33
So Moses went out of the city from Pharaoh and stretched out his hands to the LORD, and the thunder and the hail ceased, and the rain no longer poured upon the earth. 34
But when Pharaoh saw that the rain and the hail and the thunder had ceased, he sinned yet again and hardened his heart, he and his servants. 35
So the heart of Pharaoh was hardened, and he did not let the people of Israel go, just as the LORD had spoken through Moses.
