Exodus 8:10, 22,23 "......... that thou [Pharaoh] mayest know that there is none like unto the
LORD Jehovah our God. . . . .
and I will sever in that day the land of Goshen,
in which my people dwell, that no swarms of flies shall there be;
to the end that thou mayest know that
I and not thou, I and not thy gods am Jehovah
in the midst of the earth.
And I will put a division between My people and thy people."
