The pillar of cloud turning pillar of fire craft
The Israelites moved on from Sukkoth, and they camped in Etham, at the edge of the desert. HaShem went before them by day with a pillar of cloud, to guide them along the way. By night it appeared as a pillar of fire, providing them with light. They could thus travel day and night. The pillar of cloud by day and the pillar of fire at night never left their position in front of the people.
