Exodus 9:13-21 ESV
Then the LORD said to Moses, “Rise up early in the morning and present yourself before Pharaoh and say to him, ‘Thus says the LORD, the God of the Hebrews, “Let my people go, that they may serve me. For this time I will send all my plagues on you yourself, and on your servants and your people, so that you may know that there is none like me in all the earth. For by now I could have put out my hand and struck you and your people with pestilence, and you would have been cut off from the earth. But for this purpose I have raised you up, to show you my power, so that my name may be proclaimed in all the earth. You are still exalting yourself against my people and will not let them go. Behold, about this time tomorrow I will cause very heavy hail to fall, such as never has been in Egypt from the day it was founded until now. Now therefore send, get your livestock and all that you have in the field into safe shelter, for every man and beast that is in the field and is not brought home will die when the hail falls on them.”’” Then whoever feared the word of the LORD among the servants of Pharaoh hurried his slaves and his livestock into the houses, but whoever did not pay attention to the word of the LORD left his slaves and his livestock in the field.
