Exodus 40:38 WBT

³⁶  And when the cloud was taken up from over the tabernacle, the children of Israel went onward in all their journeys:

³⁷  But if the cloud was not taken up, then they journeyed not till the day that it was taken up.

³⁸  For the cloud of the LORD [was] upon the tabernacle by day, and fire was on it by night, in the sight of all the house of Israel, throughout all their journeys.
