Exodus 13:21-22

21And athe Lord went before them by day in a pillar of cloud to lead them along the way, and by night in a pillar of fire to give them light, that they might travel by day and by night. 22The pillar of cloud by day and the pillar of fire by night did not depart from before the people.

Numbers 9:18-22

18At the command of the Lord the people of Israel set out, and at the command of the Lord they camped. bAs long as the cloud rested over the tabernacle, they remained in camp. 19Even when the cloud continued over the tabernacle many days, the people of Israel ckept the charge of the Lord and did not set out. 20Sometimes the cloud was a few days over the tabernacle, and according to the command of the Lord they remained in camp; then according to the command of the Lord they set out. 21And sometimes the cloud remained from evening until morning. And when the cloud lifted in the morning, they set out, or if it continued for a day and a night, when the cloud lifted they set out. 22Whether it was two days, or a month, or a longer time, that the cloud continued over the tabernacle, abiding there, the people of Israel dremained in camp and did not set out, but when it lifted they set out.
