Exodus 40:35-37

Amplified Bible

³⁵ Moses was not able to enter the Tent of Meeting because the cloud remained on it, and the glory and brilliance of the Lord filled the tabernacle. ³⁶ In all their journeys, whenever the cloud was taken up from over the tabernacle, the Israelites would set out; ³⁷ but if the cloud was not taken up, then they did not journey on until the day when it was taken up.
