"Son of man", "son of Adam", or "as a man", are phrases used in the Hebrew Bible, various apocalyptic works of the intertestamental period, and in the Greek New Testament. In the indefinite form used in the Hebrew Bible it is a form of address, or it contrasts human beings against God and the angels, or contrasts foreign nations, which are often represented as animals in apocalyptic writings, with Israel which is represented as human, or it signifies an eschatological human figure.

Apocalypticism is the religious belief that the end of the world is imminent, even within one's own lifetime. This belief is usually accompanied by the idea that civilization will soon come to a tumultuous end due to some sort of catastrophic global event.
