'Pillar of Cloud' in the Bible

The Lord was going before them in a pillar of cloud by day to lead them on the way, and in a pillar of fire by night to give them light, that they might travel by day and by night.

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

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

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 saw the pillar of cloud standing at the entrance of the tent, all the people would arise and worship, each at the entrance of his tent.
