The cloud also of the Lord was over them by day when they marched.

and the cloud of Jehovah is on them by day, in their journeying from the camp.

And by day the cloud of the Lord went over them, when they went forward from the place where they had put up their tents.

Likewise, the cloud of the Lord was over them, throughout the day, while they proceeded.

Et nubes Jehovae erat super eos interdiu, dum proficiscerentur e castris.

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.

By day - And by night too, as was expressed before. So we must learn to compare places of scripture, and to supply the defects of one out of another, as we do in all authors.
