'Someone' in the Bible

Among the lamp stands there was someone like the Son of Man. He was wearing a long robe with a gold sash around his chest.

They were not allowed to kill them, but were only allowed to torture them for five months. Their torture was like the pain of a scorpion when it stings someone.

Then I looked, and there was a white cloud! On the cloud sat someone who was like the Son of Man, with a gold victor's crown on his head and a sharp sickle in his hand.
