Exodus 9:27-35

27And Pharaoh sent, and called Moses and Aaron, and said to them, I have sinned this time: Jehovah is the righteous [one], but I and my people are the wicked [ones]. 28Intreat Jehovah that it may be enough, that there be no more thunder of 1God and hail; and I will let you go, and ye shall stay no longer! 29And Moses said to him, When I go out of the city, I will spread out my hands to Jehovah: the thunder will cease, and there will be no more hail; that thou mayest know that the earth is Jehovah's. 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. 35And the heart of Pharaoh was stubborn, neither would he let the children of Israel go, as Jehovah had spoken by Moses.
