Numbers 10:34

And the cloud of the Lord was upon them by day ,.... Not only upon the tabernacle, and upon the ark particularly, but it spread itself in journeying over the whole body of the people, and therefore said to be a covering to them from the heat of the sun, Psalm 105:39 ; as well as it was a guide unto them, and a token of the divine Presence with them, see Isaiah 4:5

when they went out of the camp ; or out of the place of their encampment, when they removed from Sinai; and appears from, hence that it was in the daytime.
