15. By now I could have used my power to kill you and your people with a plague that would have wiped you off the earth.
16. But I have spared you for this reason. I want to show you my power and make my name famous throughout the earth.
17. You are still blocking my people from leaving.
18. So, at this time tomorrow I will send the worst hailstorm that has ever happened in Egypt since the beginning of its history.
