Exodus 8:21-23

21st Century King James Version

²¹ Else, if thou wilt not let My people go, behold, I will send swarms of flies upon thee, and upon thy servants and upon thy people and into thy houses; and the houses of the Egyptians shall be full of swarms of flies, and also the ground whereon they are.

²² And I will sever in that day the land of Goshen in which My people dwell, that no swarms of flies shall be there, to the end thou mayest know that I am the Lord in the midst of the earth.

²³ And I will put a division between My people and thy people. Tomorrow shall this sign be.’”
