Charles Ellicott Commentary Mark 13:3

"And as he sat on the mount of Olives over against the temple, Peter and James and John and Andrew asked him privately," — Mark 13:3 (ASV)

Opposite the temple.—The view that the position commanded, and which St. Mark alone mentions, made all that followed more vivid and impressive. It may well have been at or near the very spot where, a few days before, He had paused when He beheld the city and wept over it (Luke 19:41).

Peter and James and John and Andrew.—The list of names is noticeable:

1. as it is given by St. Mark only;
2. as it is the only instance where the name of Andrew appears together with the three who, on other occasions, were within the inner circle of companionship;
3. and in the position given to Andrew (last in the list, despite being the first disciple called (John 1:41)).
