Numbers 9:16-18

16So it was always: the cloud covered it by day
Septuagint, Syriac, Vulgate; Hebrew lacks  by day
and the appearance of fire by night.
17And whenever the cloud blifted from over the tent, after that the people of Israel set out, and in the place where the cloud settled down, there the people of Israel camped. 18At the command of the Lord the people of Israel set out, and at the command of the Lord they camped. cAs long as the cloud rested over the tabernacle, they remained in camp.
