Exodus 9, 13 – 18 „Then the LORD spoke to Moses: Early tomorrow morning present yourself to Pharaoh and say to him: Thus says the LORD, the God of the Hebrews: Let my people go to serve me, 14for this time I will unleash all my blows upon you and your servants and your people, so that you may know that there is none like me anywhere on earth. 15For by now I should have stretched out my hand and struck you and your people with such pestilence that you would have vanished from the earth. 16But this is why I have let you survive: to show you my power and to make my name resound throughout the earth! 17Will you continue to exalt yourself over my people and not let them go? 18At this time tomorrow, therefore, I am going to rain down such fierce hail as there has never been in Egypt from the day it was founded up to the present”.
