Exodus 9:30-34

30But as for you and your servants, I know that you do not yet fear the Lord God.”

31(Now the flax and the barley were struck by the hail, for the barley had ripened and the flax was in bud.

32But the wheat and the spelt were not struck, for they are later crops.)

33So Moses left Pharaoh, went out of the city, and spread out his hands to the Lord, and the thunder and the hail ceased, and the rain stopped pouring on the earth.

34When Pharaoh saw that the rain and hail and thunder ceased, he sinned again: both he and his servants hardened their hearts.
