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

And Jehovah went before them by day in a pillar of cloud, to lead them the way, and by night in a pillar of fire, to give them light, that they might go by day and by night:

and 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 came not near the other all the night.
