13. The Lord said to Moses, “Get up early in the morning, stand before Pharaoh, and tell him, ‘Thus says the Lord, the God of the Hebrews: “Release my people so that they may serve me!
14. For this time I will send all my plagues on your very self and on your servants and your people, so that you may know that there is no one like me in all the earth.
15. For by now I could have stretched out my hand and struck you and your people with plague, and you would have been destroyed from the earth.
16. But for this purpose I have caused you to stand: to show you my strength, and so that my name may be declared in all the earth.
17. You are still exalting yourself against my people by not releasing them.
18. I am going to cause very severe hail to rain down about this time tomorrow, such hail as has never occurred in Egypt from the day it was founded until now.
