The Israelites crossed the Sinai and camped in Etham on the other side of the desert. The Bible tells us that God went with them. There was a pillar of cloud during the day and a pillar of fire during the day. This was physical evidence that God was actually with them. All the people could simply look up and see this pillar. If they could see it, they were going in the right direction. Now this wasn’t just a wisp of smoke during the day or a tendril of fire in the night.
