The Cloud Separates the Camps

Exodus 14:19-20

And the messenger of God, who is going before the camp of Israel, journeyeth and goeth at their rear; and the pillar of the cloud journeyeth from their front, and standeth at their rear,

and cometh in between the camp of the Egyptians and the camp of Israel, and the cloud and the darkness are, and he enlighteneth the night, and the one hath not drawn near unto the other all the night.
