'Brightness' in the Bible

I looked, and behold, a stormy wind came out of the north, a great cloud, with flashing lightning, and a brightness around it, and out of its midst as it were glowing metal, out of the midst of the fire.

I saw as it were glowing metal, as the appearance of fire within it all around, from the appearance of his waist and upward; and from the appearance of his waist and downward I saw as it were the appearance of fire, and there was brightness around him.

As the appearance of the rainbow that is in the cloud in the day of rain, so was the appearance of the brightness all around. This was the appearance of the likeness of the glory of Yahweh. When I saw it, I fell on my face, and I heard a voice of one that spoke.

Then I saw, and behold, a likeness as the appearance of fire; from the appearance of his waist and downward, fire; and from his waist and upward, as the appearance of brightness, as it were glowing metal.

The glory of Yahweh mounted up from the cherub, [and stood] over the threshold of the house; and the house was filled with the cloud, and the court was full of the brightness of Yahweh's glory.

therefore, behold, I will bring strangers on you, the terrible of the nations; and they shall draw their swords against the beauty of your wisdom, and they shall defile your brightness.

Your heart was lifted up because of your beauty; you have corrupted your wisdom by reason of your brightness: I have cast you to the ground; I have laid you before kings, that they may see you.
