'Cloud' in the Bible

Then the angel replied to her, “The Holy Spirit will come upon you, and the power of the Most High will overshadow you [like a cloud]; for that reason the holy (pure, sinless) Child shall be called the Son of God.

While he thus spake, there came a cloud, and overshadowed them: and they feared as they entered into the cloud.

And there came a voice out of the cloud, saying, This is my beloved Son: hear him.

And he said also to the people, When ye see a cloud rise out of the west, straightway ye say, There cometh a shower; and so it is.

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