Exodus 16:9,10

And Moses spake unto Aaron, Say unto all the congregation of the children of Israel, Come near before the LORD: for he hath heard your murmurings.

Come near before the Lord ... they looked toward the wilderness. They were called to leave their tents, and stand looking toward the wilderness of Sin, over which the cloud was hovering; and in the awful phase which that cloud then exhibited-in the light that glared from it they witnessed the majesty of God; while in the sounds that were heard from it they received at once a rebuke to their own reproaches, and a confirmation of the veracity of His servants.
