Thematic Bible: The pillar of cloud and fire

And the angel of God which went before the host of Israel, removed and went behind them. And the clouden pillar that was before them removed and stood behind them and went between the host of the Egyptians and the host of Israel. It was a dark cloud, and gave light by night: so that all the night long the one could not come at the other.

And the LORD went before them by day in a pillar of a cloud to lead them the way: and by night in a pillar of fire to give them light: that they might go both by day and night. And the pillar of the cloud never departed by day nor the pillar of fire by night out of the people's sight.
