{Wherefore we faint not} (dio ouk egkakoumen). Repeats
from verse  1 . {Our outward man} (ho ex(9320)h(886d)(936e) anthr(9370)os),
{our inward man} (ho es(9320)h(886d)(936e)). In  Ro 7:22  Col 3:9  Eph

and the lower natures (the spirit and the flesh). "Here the decay
(diaphtheiretai) of the bodily organism is set over against the
growth in grace (anakainoutai, is refreshed) of the man
himself" (Bernard). Plato (_Republ_. ix, p. 589) has ho entos
anthr(9370)os. Cf. "the hidden man of the heart" ( 1Pe 3:4 ). {Day
by day} (h(886d)er(8369) kai h(886d)er(8369)). This precise idiom is not in LXX
nor rest of N.T. It may be colloquial use of locative in
repetition.
