Exodus 40:37 YLT

³⁵  and Moses hath not been able to go in unto the tent of meeting, for the cloud hath tabernacled on it, and the honour of Jehovah hath filled the tabernacle.

³⁶  And in the going up of the cloud from off the tabernacle the sons of Israel journey in all their journeys;

³⁷  and if the cloud go not up then they journey not, until the day of its going up:

³⁸  for the cloud of Jehovah 'is' on the tabernacle by day, and fire is in it by night, before the eyes of all the house of Israel in all their journeys.
