{For full-grown men} (	elei(936e)). Predicate genitive. The
word is for adults, relative perfection (	eleioi) in contrast
with babes as in  1Co 2:6  3:1  13:11  Php 3:15  Eph 4:4 , not
absolute perfection ( Mt 5:48 ). {Their senses} (	a
aisth(8874)(8872)ia). The organs of perception (Stoic term for sense
organs) from aisthanomai ( Lu 9:45 ), in Plato, Galen,
Hippocrates, here only in N.T. {Exercised} (gegumnasmena).
Perfect passive participle of gumnaz(935c), to exercise (naked,
gumnos). Galen uses aisth(8874)(8872)ia gegumnasmena together after
ech(935c) as we have here. For this predicate use of the participle
with ech(935c) see  Lu 13:6  14:19f . "By reason of use" one gains
such skill. {To discern} (pros diakrisin). "For deciding
between" (from diakrin(935c)), old word with ablative kalou te kai
kakou (between good and evil). See  1Co 12:1  Rom 14:1 .
