Exodus 9:27-35

27And Pharaoh sent, and called for Moses and Aaron, and said to them, I have sinned this time: the LORD is righteous, and I and my people are wicked. 28Entreat 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.1 29And Moses said to him, As soon as I am gone out of the city, I will spread abroad my hands to 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. 30But as for thee and thy servants, I know that ye will not yet fear the LORD God. 31And the flax and the barley were smitten: for the barley was in the ear, and the flax was in bud. 32But the wheat and the rye were not smitten: for they were not grown up.2 33And Moses went out of the city from Pharaoh, and spread abroad his hands to the LORD: and the thunders and hail ceased, and the rain was not poured upon the earth. 34And when Pharaoh saw that the rain and the hail and the thunders had ceased, he sinned yet more, and hardened his heart, he and his servants. 35And the heart of Pharaoh was hardened, neither would he let the children of Israel go; as the LORD had spoken by Moses.3
