'Cloud' in the Bible

But while he was thus speaking, there came a cloud which spread over them; and they were awe-struck when they had entered into the cloud.

Then there came a voice from within the cloud: "This is My Son, My Chosen One: listen to Him."

Then He said to the people also, "When you see a cloud rising in the west, you immediately say, 'There is to be a shower;' and it comes to pass.

And then will they see the Son of Man coming in a cloud with great power and glory.
