Exodus 9:30-34

30But as to thee and thy bondmen, I know that ye do not yet fear Jehovah Elohim.

31And the flax and the barley were smitten; for the barley was in the ear, and the flax was bolled.

32But the wheat and the spelt were not smitten; for they were not come out into ear.

33And Moses went out of the city from Pharaoh, and spread out his hands to Jehovah; and the thunders and hail ceased, and the rain was not [any more] poured on the earth.

34And Pharaoh saw that the rain and the hail and the thunders had ceased, and he sinned yet more, and hardened his heart, he, and his bondmen.
