so that the priests could not stand to minister by reason of the cloud: for the glory of Yahweh filled the house of God.
The appearance of the glory of Yahweh was like devouring fire on the top of the mountain in the eyes of the children of Israel.
Then I said, "Woe is me! For I am undone, because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for my eyes have seen the King, Yahweh of Armies!"
The temple was filled with smoke from the glory of God, and from his power. No one was able to enter into the temple, until the seven plagues of the seven angels would be finished.
Moses wasn't able to enter into the Tent of Meeting, because the cloud stayed on it, and Yahweh's glory filled the tabernacle.
