'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.

Immediately I was in the Spirit, and a throne was standing in heaven with someone seated on it!

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 there was given me a measuring rod like a staff; and someone said, “Get up and measure the temple of God and the altar, and those who worship in it.

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.

Then I heard someone from the altar say:Yes, Lord God, the Almighty,true and righteous are Your judgments.
