It is a night to be much observed to the LORD for bringing them out from the land of Egypt. This is that night of the LORD, to be much observed of all the children of Israel throughout their generations.

The LORD went before them by day in a pillar of cloud, to lead them on their way, and by night in a pillar of fire, to give them light, that they might go by day and by night:

It came between the camp of Egypt and the camp of Israel; and there was the cloud and the darkness, yet gave it light by night: and the one did not come near the other all the night.
