Exodus 8:22-24

Wycliffe Bible

²² And in that day I shall make wonderful the land of Goshen, in which my people is, that flies be not there; and that thou know that I am the Lord in the midst of [the] earth; (But on that day I shall protect the land of Goshen, where my people be, so that there shall be no flies there; and so that thou shalt know that I, the Lord, am in the midst of the land;)

²³ and I shall set parting betwixt my people and thy people; this sign shall be tomorrow (this miracle shall come tomorrow).

²⁴ And the Lord did so. And a most grievous fly, that is, (a) multitude of flies, came into the house of Pharaoh, and into the houses of his servants, and into all the land of Egypt; and the land was corrupted of such flies (and the land was ruined by such a multitude of flies).
