Exodus 40:34-38

Thomson(i) 34 the cloud covered the tabernacle of the testimony, and the tabernacle was filled with the glory of the Lord 35 so that Moses could not go into the tabernacle of the testimony, because the cloud overshadowed it and with the glory of the Lord the tabernacle was filled. 36 Now when the cloud ascended from the tabernacle, the Israelites prepared to march with their baggage. 37 But if the cloud did not ascend they did not prepare to march till the day when the cloud ascended. 38 For there was a cloud on the tabernacle by day and in the night there was a fire on it in the sight of all Israel throughout all their journeyings.
