Exodus 40

Exodus 40:35

And Moses was not able to enter into the tent of the congregation, because the cloud abode thereon, and the glory of the LORD filled the tabernacle.

So Moses, at that time, could not, for reverence of the place, enter into the tabernacle of the congregation; because God, now, at the first consecration of it, did so gloriously manifest himself; not only in the sign of the cloud upon the tabernacle, but also of exceeding glory and brightness within the tabernacle.
