Albert Barnes on Matthew 24:1

And Jesus went out. He was going over to the Mount of Olives, Mt 24:3.

The buildings of the temple. The temple itself, with the surrounding courts, porches, and other edifices. Mt 21:12. Mark says, that they particularly pointed out the stones of the temple, as well as the buildings. "In that temple," says Josephus, the Jewish historian, "were several stones which were forty-five cubits in length, five in height, and sixth in breadth;" that is, more than seventy feet long, ten wide, and eight high. These stones, of such enormous size, were principally used in building the high wall on the east side, from the base to the top of the mountain. They were also, it is said, beautifully painted with variegated colours.
