The mount of Olives is the olive-shaped body at the base of the brain, the hypoglossal region where the nerve of speech and the deep centers meet, and to sit there is to rest awareness at that inner seat. The ones who come privately are the meditators, and their question about the end of the world is not about a globe burning but about the ending of the outer, literal mind so the inner reign can begin.
The coming and the end asked after here happen inside the skull, at that olive in the brain where the higher state dawns. The end of the world is the close of the age of literal seeing within a person, the moment the outward-facing mind gives way. The whole exchange takes place at an anatomical point in the head, asked in the privacy of the inner stillness.

Disciples: those who meditate, coming inward in private to ask of the higher state
