Numbers 9:20

Then the cloud covered the tent of meeting, and the glory of Yahweh filled the tabernacle.

but if the cloud was not taken up, then they did not set out until the day when it was taken up.

Now the cloud of Yahweh was over them by day when they set out from the camp.

who goes before you on your way, to spy out a place for you to encamp, in fire by night and cloud by day, to show you the way in which you should go.

then Yahweh will create over the whole area of Mount Zion and over her convocation a cloud by day, even smoke, and the brightness of a flaming fire by night; for over all the glory will be a canopy.
