'Pillar of Cloud' in the Bible

Now the Lord was going before them by day in a pillar of cloud to lead them in the way, and by night in a pillar of fire to give them light, so that they could travel day or night.

He did not remove the pillar of cloud by day nor the pillar of fire by night from before the people.

The angel of God, who was going before the camp of Israel, moved and went behind them, and the pillar of cloud moved from before them and stood behind them.

And whenever Moses entered the tent, the pillar of cloud would descend and stand at the entrance of the tent, and the Lord would speak with Moses.

When all the people would see the pillar of cloud standing at the entrance of the tent, all the people, each one at the entrance of his own tent, would rise and worship.
