'Pillar' in the Bible

The [presence of the] Lord was going before them by day in a pillar (column) of cloud to lead them along the way, and in a pillar of fire by night to give them light, so that they could travel by day and by night.

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

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

So it happened at the early morning watch [before dawn], that the Lord looked down on the army of the Egyptians through the pillar of fire and cloud and put them in a state of confusion.

Whenever Moses entered the tent, the pillar of cloud would descend and stand at the doorway of the tent; and the Lord would speak with Moses.

When all the people saw the pillar of cloud standing at the tent door, all the people would rise and worship, each at his tent door.
