Exodus 8:20-24

20And the LORDH3068 saidH3651 unto Moses, Rise upH935 early in the morning, and standH935 beforeH6440 PharaohH6547; lo, he cometh forth to the water; and say unto him, ThusH3651 saith the LORDH3068, LetH3651 my peopleH776 goH935, that they may serveH6440 meH6440.

21Else, if thou wilt notH776 let my peopleH776 go, behold, I will send swarms of flies uponH7121 thee, and uponH7121 thy servants, and uponH7121 thy peopleH776, and intoH413 thy houses: and the houses of the Egyptians shall be full of swarms of flies, and also the groundH776 whereon they are.

22And I will sever in that dayH4872 the land of Goshen, in whichH5869 my peopleH3808 dwell, that noH3808 swarms of flies shall be there; to the end thou mayest know that I am the LORDH3068 in the midst of the earth.

23And I will put a division between my peopleH834 and thy peopleH834: by tomorrow shall this sign be.

24And the LORDH3068 didH3808 soH7971; and there cameH559 grievous swarms of flies intoH6547 the house of PharaohH6547, and intoH6547 his servants’ houses: and in all the land of Egypt the land was corrupted by reason of the swarms of flies.
