Exodus 9:13-16

13And the LORD said to Moses, Rise early in the morning, and stand before Pharaoh, and say to him, Thus saith the LORD God of the Hebrews, Let my people go, that they may serve me. 14For I will at 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. 15For now I will stretch out my hand, that I may smite thee and thy people with pestilence; and thou shalt be cut off from the earth. 16And in very deed for this cause have I raised thee up, to show in thee my power; and that my name may be declared throughout all the earth.1
