Exodus 8:22; Exodus 11:7

22 But on that day gI will set apart the land of Goshen, where my people dwell, so that no swarms of flies shall be there, hthat you may know that I am the Lord in the midst of the earth.1


But not a dog shall growl zagainst any of the people of Israel, either man or beast, that you may know that the Lord amakes a distinction between Egypt and Israel.
