{Went out from the temple} (exelth(936e) apo tou hierou). All
the discourses since  Mt 21:23  have been in the temple courts
(hieron, the sacred enclosure). But now Jesus leaves it for
good after the powerful denunciation of the scribes and Pharisees
in chapter 23. His public teaching is over. It was a tragic
moment. As he was going out (eporeueto, descriptive imperfect)
the disciples, as if to relieve the thought of the Master came to
him (pros(886c)thon) to show (epideixai, ingressive aorist
infinitive) the buildings of the temple (	as oikodomas tou
hierou). They were familiar to Jesus and the disciples, but
beautiful like a snow mountain (Josephus, _Wars_ V,5,6), the
monument that Herod the Great had begun and that was not yet
complete ( Joh 2:20 ). Great stones were there of polished
marble.
