TSK · Numbers 10:34

For the cloud of the LORD was on the tabernacle by day, but fire would be on it at night, in plain view of all the house of Israel, throughout all their journeys.

You guided them with a pillar of cloud by day and with a pillar of fire by night to illumine for them the path they were to travel.

He spread out a cloud for a cover, and provided a fire to light up the night.
