'Cloud' in the Bible

Now when the priests had come out of the holy place, the house of the Lord was full of the cloud,

So that the priests were not able to keep their places to do their work because of the cloud, for the house of the Lord was full of the glory of the Lord.

And the seventh time he said, I see a cloud coming up out of the sea, as small as a man's hand. Then he said, Go up and say to Ahab, Get your carriage ready and go down or the rain will keep you back.
