{As they passed by in the morning} (paraporeuomenoi
pr(9369)). Literally, passing by in the morning. The next morning.
They went back by the lower road up the Mount of Olives and came
down each morning by the steep and more direct way. Hence they
saw it.  Mt 21:20  does not separate the two mornings as Mark
does. {From the roots} (ek riz(936e)). Mark alone gives this detail
with ex(8872)ammen(886e) perfect passive predicate participle from
x(8872)ain(935c).
