Exodus 40:35-37

American Standard Version

³⁵ And Moses was not able to enter into the tent of meeting, because the cloud abode thereon, and the glory of Jehovah filled the tabernacle. ³⁶ And when the cloud was taken up from over the tabernacle, the children of Israel went onward, throughout all their journeys: ³⁷ but if the cloud was not taken up, then they journeyed not till the day that it was taken up.
