What Does the Title Satan Mean in Job 1:6–12?
In Job 1:6–12 the figure called Satan appears as an accuser holding an office, not a personal name, and he answers to God. The passage fixes the boundary of his action in Yahweh's hands, not his own.

1 John 4:4: Greater Is He Who Is in You

Mark 9:38–41: The Outsider Casting Out Demons
