'Pillar of Cloud' in the Bible

The Lord went ahead of them in a pillar of cloud to lead them on their way during the day and in a pillar of fire to give them light at night, so that they could travel day or night.

The pillar of cloud by day and the pillar of fire by night never left its place in front of the people.

Then the Angel of God, who was going in front of the Israelite forces, moved and went behind them. The pillar of cloud moved from in front of them and stood behind them.

When Moses entered the tent, the pillar of cloud would come down and remain at the entrance to the tent, and the Lord would speak with Moses.

As all the people saw the pillar of cloud remaining at the entrance to the tent, they would stand up, then bow in worship, each one at the door of his tent.
