Exodus 8:21-24

JPS_ASV_Byz(i) 21 (8:17) 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 (8:18) And I will set apart in that day the land of Goshen, in which My people dwell, that no swarms of flies shall be there; to the end that thou mayest know that I am the LORD in the midst of the earth. 23 (8:19) And I will put a division between My people and thy people - by to-morrow shall this sign be.' 24 (8:20) And the LORD did so; and there came grievous swarms of flies into the house of Pharaoh, and into his servants' houses; and in all the land of Egypt the land was ruined by reason of the swarms of flies.
