It is a night to be observed for the Lord for having brought them out from the land of Egypt; this night is for the Lord, to be observed by all the sons of Israel throughout their generations.

The Lord was going before them in a pillar of cloud by day to lead them on the way, and in a pillar of fire by night to give them light, that they might travel by day and by night.

So it came between the camp of Egypt and the camp of Israel; and there was the cloud along with the darkness, yet it gave light at night. Thus the one did not come near the other all night.
