Exodus 9:30-34

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

(Now the flax and the barley were ruined, for the barley was in the ear and the flax was in bud.

But the wheat and the spelt were not ruined, for they ripen late.)

So Moses left the city from his meeting with Pharaoh, and spread out his hands to the Lord; and the thunder and the hail stopped, and rain no longer poured on the earth.

But when Pharaoh saw that the rain and the hail and the thunder had stopped, he sinned again and hardened his heart, he and his servants.
