Exodus 8:22-24

Young's Literal Translation

²² `And I have separated in that day the land of Goshen, in which My people are staying, that the beetle is not there, so that thou knowest that I [am] Jehovah in the midst of the land,

²³ and I have put a division between My people and thy people: to-morrow is this sign.'

²⁴ And Jehovah doth so, and the grievous beetle entereth the house of Pharaoh, and the house of his servants, and in all the land of Egypt the land is corrupted from the presence of the beetle.
