Exodus 40:36-38

NHEB(i) 36 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 wasn't taken up, then they did not travel until the day that it was taken up. 38 For the cloud of the LORD was on the tabernacle by day, and there was fire in the cloud by night, in the sight of all the house of Israel, throughout all their journeys.
