Luke 9:34-35; Luke 12:54; Luke 21:27

34 While he was saying this, a cloud formed and began to overshadow them; and they were afraid as they entered the cloud. 35 Then a voice came out of the cloud, saying, "This is My Son, My Chosen One; listen to Him!"
54 And He was also saying to the crowds, "When you see a cloud rising in the west, immediately you say, 'A shower is coming,' and so it turns out.
27 "Then they will see THE SON OF MAN COMING IN A CLOUD with power and great glory.
