'Cloud' in the Bible

who went before you along the way, in fire by night and in a cloud by day, to seek a place for you to make camp and to show you the way in which you should go.

You approached and stood at the foot of the mountain, and the mountain burned with fire to the [very] heart of the heavens: darkness, cloud and thick gloom.

“The Lord spoke these words with a great voice to all your assembly at the mountain out of the midst of the fire, the cloud, and the thick darkness, and He added no more. He wrote these commandments on two tablets of stone and gave them to me.

Then the Lord appeared in the tent in a pillar of cloud, and the pillar of cloud stood beside the doorway of the tent.
