'Pillar of Cloud' in the Bible

And LORD 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.

The pillar of cloud by day, and the pillar of fire by night departed not from before the people.

And the agent of God, who went before the camp of Israel, moved and went behind them, and the pillar of cloud moved from before them, and stood behind them.

And it came to pass, when Moses entered into the tent, the pillar of cloud descended, and stood at the door of the tent, and [LORD] spoke with Moses.

And all the people saw the pillar of cloud stand at the door of the tent. And all the people rose up and worshipped, every man at his tent door.
