{He was subject unto them} ((886e) hupotassomenos autois).
Periphrastic imperfect passive. He continued subject unto them,
this wondrous boy who really knew more than parents and rabbis,
this gentle, obedient, affectionate boy. The next eighteen years
at Nazareth ( Lu 3:23 ) he remained growing into manhood and
becoming the carpenter of Nazareth ( Mr 6:3 ) in succession to
Joseph ( Mt 13:55 ) who is mentioned here for the last time. Who
can tell the wistful days when Jesus waited at Nazareth for the
Father to call him to his Messianic task? {Kept} (diet(8872)ei).
Imperfect active. Ancient Greek word (diat(8872)e(935c)), but only here
and  Ac 15:29  in the N.T. though in  Ge 37:11 . She kept
thoroughly (dia) all these recent sayings (or things,

h(886d)ata). In  2:19  sunet(8872)ei is the word used of Mary after
the shepherds left. These she kept pondering and comparing all
the things. Surely she has a full heart now. Could she foresee
how destiny would take Jesus out beyond her mother's reach?
