Mark 13:3
As Jesus was sitting on the Mount of Olives opposite the temple, Peter, James, John and Andrew asked him privately — the Mount of Olives setting is eschatologically significant (Zechariah 14:4) and provides the physical vantage point from which the temple is visible across the Kidron Valley. The private question is from the inner three (Peter, James, John) plus Andrew — the same group as in the raising of Jairus's daughter. The private asking follows the Mark pattern: public teaching, private clarification.
