Exodus 9:13-21

And Jehovah said unto Moses, Rise up early in the morning, and stand before Pharaoh, and say unto him, Thus saith Jehovah, the God of the Hebrews, Let my people go, that they may serve me. For I will this time send all my plagues upon thy heart, and upon thy servants, and upon thy people; that thou mayest know that there is none like me in all the earth. For now I had put forth my hand, and smitten thee and thy people with pestilence, and thou hadst been cut off from the earth: but in very deed for this cause have I made thee to stand, to show thee my power, and that my name may be declared throughout all the earth. As yet exaltest thou thyself against my people, that thou wilt not let them go? Behold, to-morrow about this time I will cause it to rain a very grievous hail, such as hath not been in Egypt since the day it was founded even until now. Now therefore send, hasten in thy cattle and all that thou hast in the field; for every man and beast that shall be found in the field, and shall not be brought home, the hail shall come down upon them, and they shall die. He that feared the word of Jehovah among the servants of Pharaoh made his servants and his cattle flee into the houses: and he that regarded not the word of Jehovah left his servants and his cattle in the field.
