THE MURMURING PEOPLE ENCOURAGED

PILLARS OF CLOUD AND FIRE

Pillars Of Cloud And Fire. The [presence of the] LORD was going before them by day in a pillar (column) of cloud to lead them along the way, and in a pillar of fire by night to give them light, so that they could travel by day and by night.
He did not withdraw the pillar of cloud by day, nor the pillar of fire by night, from going before the people.

THE FEAST OF UNLEAVENED BREAD

Then the LORD said to Moses, “Stretch out your hand toward the sky, so that darkness may come over the land of Egypt, a darkness which [is so awful that it] may be felt.”
