Exodus 13:
21 And the Lord went before them by day in a pillar of cloud to lead the way, and by night in a pillar of fire to give them light, so as to go by day and night. 22He did not take away the pillar of cloud by day or the pillar of fire by night from before the people.
There were two different types of pillars depending on the time of the day.
Exodus 14:
24 Now it came to pass, in the morning watch, that the Lord looked down upon the army of the Egyptians through the pillar of fire and cloud, and He troubled the army of the Egyptians.
Was this a third type of pillar with fire and cloud at the same time, like half and half?
