Exodus 9
28 Ref Pray to Yahweh; for there has been enough of mighty thunderings and hail. I will let you go, and you shall stay no longer."
29 Ref Moses said to him, "As soon as I have gone out of the city, I will spread abroad my hands to Yahweh. The thunders shall cease, neither shall there be any more hail; that you may know that the earth is Yahweh's.
