Cloud of Glory was Designed to Guide Israel

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.

You in Your great compassion did not forsake them in the wilderness. By day the pillar of cloud never turned away from guiding them on their path; and by the night the pillar of fire illuminated the way they should go.
