Deuteronomy 1:33
Who went in the way before you, to search you out a place to pitch your tents in, in fire by night, to shew you by what way ye should go, and in a cloud by day.
Who went in the way before you, to search you out a place to pitch your tents in,.... For when the cloud was taken up they journeyed, and when that rested, there they pitched their tents; and hereby they were directed to places the most convenient for water for them and their flocks, or for safety from those that might annoy them:
in fire by night, to show you by what way ye should go; which otherwise they could not have found in dark nights, in which they sometimes travelled, and in, a wilderness where there were no tracks, no beaten path, no common way:
and in a cloud by day; to shelter them from the scorching sun, where there were no trees nor hedges to shade them, only rocky crags and hills.
