Exodus 9:27-31 King James Version (KJV)

27. And Pharaoh sent, and called for Moses and Aaron, and said unto them, I have sinned this time: the Lord is righteous, and I and my people are wicked.

28. Entreat the Lord (for it is enough) that there be no more mighty thunderings and hail; and I will let you go, and ye shall stay no longer.

29. And Moses said unto him, As soon as I am gone out of the city, I will spread abroad my hands unto the Lord; and the thunder shall cease, neither shall there be any more hail; that thou mayest know how that the earth is the Lord’s.

30. But as for thee and thy servants, I know that ye will not yet fear the Lord God.

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