The heart of Par`oh was hardened, and he didn't let the children of Yisra'el go, just as the LORD had spoken through Moshe.
I know that the king of Egypt won't give you permission to go, no, not by a mighty hand.
The LORD said to Moshe, *When you go back into Egypt, see that you do before Par`oh all the wonders which I have put in your hand, but I will harden his heart and he will not let the people go.
Par`oh's heart was hardened, and he didn't listen to them; as the LORD had spoken.
When Par`oh saw that the rain and the hail and the thunders were ceased, he sinned yet more, and hardened his heart, he and his servants.
