'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.

But even as he was saying this, a cloud formed and began to overshadow them; and they were [greatly] afraid as they entered the cloud.

Then a voice came out of the cloud, saying, “This is My beloved Son, My Chosen One; listen and obey and yield to Him!”

He also said to the crowds, “When you see a cloud rising in the west, you immediately say, ‘It is going to rain,’ and that is how it turns out.

Then they will see the Son of Man coming in a cloud with [transcendent, overwhelming] power [subduing the nations] and with great glory.
