Exodus 16:10

And it came to pass, as Aaron spoke to the whole congregation of the children of Israel,.... Before he had well done speaking:

that they looked toward the wilderness; they were already in the wilderness of Sin, and they looked straight forward toward that part of it which was yet before them, or to the wilderness of Sinai, which was right onward, and whither they were travelling:

and, behold, the glory of the Lord appeared in the cloud; which went before them; there was a more than common brightness in it, an effulgence and beam of light and glory shining in it. Christ, the brightness of his Father's glory, and the express image of his person, appeared in it, in some visible displays of his majesty, which made it very observable to them.
