One of the Dead Sea Scrolls (4Q535, Manuscript B) is written from Amram's point of view, and hence has been dubbed the Visions of Amram. The document is dated to the 2nd century BC and, in the form of a vision, briefly discusses dualism and the Watchers:
I saw Watchers in my vision, the dream-vision. Two men were fighting over me…holding a great contest over me. I asked them, 'Who are you, that you are thus empowered over me?' They answered, 'We have been empowered and rule over all mankind.' They said to me, 'Which of us do you choose to rule you?' I raised my eyes and looked. One of them was terrifying in his appearance, like a serpent, his cloak, many-colored yet very dark….And I looked again, and in his appearance, his visage like a viper….I replied to him, 'This Watcher, who is he?' He answered, 'This Watcher…his three names are Belial and Prince of Darkness and King of Evil.' I said (to the other Watcher), 'My lord, what dominion (have you?)' He answered, 'You saw (the viper), and he is empowered over all Darkness, while I (am empowered over all Light.)…My three names are Michael, Prince of Light and King of Righteousness.[16]
Who really are the characters that appear there?
Hint is not Satan or God.
