Exodus 8:17-19

Complete Jewish Bible

^17 (21) Otherwise, if you won’t let my people go, I will send swarms of insects on you, your servants and your people, and into your houses. The houses of the Egyptians will be full of swarms of insects, and likewise the ground they stand on. ^18 (22) But I will set apart the land of Goshen, where my people live — no swarms of insects will be there — so that you can realize that I am Adonai, right here in the land. (vi) ^19 (23) Yes, I will distinguish between my people and your people, and this sign will happen by tomorrow.”’”
