Exodus 40:36-38 Young's Literal Translation Of The Holy Bible (YLT98)

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.
