God: The Pillar of Cloud
Source: Nav
Exodus 13:21
And the LORD went before them in a pillar of cloud to guide their way by day, and in a pillar of fire to give them light by night, so that they could travel by day or night.
Exodus 14:19, 20
And the angel of God, who had gone before the camp of Israel, withdrew and went behind them. The pillar of cloud also moved from before them and stood behind them, / so that it came between the camps of Egypt and Israel. The cloud was there in the darkness, but it lit up the night. So all night long neither camp went near the other.
