because
Ezekiel 43:2-4
2
And, behold, the glory of the God of Israel came from the way of the east: and his voice was like a noise of many waters: and the earth shined with his glory.
3
And it was according to the appearance of the vision which I saw, even according to the vision that I saw when I came to destroy the city: and the visions were like the vision that I saw by the river Chebar; and I fell upon my face.
4
And the glory of the LORD came into the house by the way of the gate whose prospect is toward the east.
Exodus 24:10
And they saw the God of Israel: and there was under his feet as it were a paved work of a sapphire stone, and as it were the body of heaven in his clearness.
Isaiah 6:1-5
1
In the year that king Uzziah died I saw also the Lord sitting upon a throne, high and lifted up, and his train filled the temple.
2
Above it stood the seraphims: each one had six wings; with twain he covered his face, and with twain he covered his feet, and with twain he did fly.
3
And one cried unto another, and said, Holy, holy, holy, is the LORD of hosts: the whole earth is full of his glory.
4
And the posts of the door moved at the voice of him that cried, and the house was filled with smoke.
5
Then said I, 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 mine eyes have seen the King, the LORD of hosts.
