What was the pillar of fire crossing the red sea?

The pillar of fire is a biblical reference found in the Book of Exodus, where it represents God's guiding presence as the Israelites escaped from Egypt. As they fled, the pillar of fire illuminated their night and provided direction, symbolizing divine protection and guidance. While the crossing of the Red Sea is a separate miraculous event where the waters parted to allow the Israelites to escape from the pursuing Egyptian army, the pillar of fire served to reassure and lead them during their journey.
