{He that is a hireling} (ho misth(9374)os). Old word from
mistho(935c), to hire ( Mt 20:1 ) from misthos (hire, wages,  Lu
10:7 ), in N.T. only in this passage. Literally, "the hireling
and not being a shepherd" (ho misth(9374)os kai ouk (936e) poim(886e)).
Note ouk with the participle (936e) to emphasize the certainty
that he is not a shepherd in contrast with m(8820)eiserchomenos in
verse  1  (conceived case). See same contrast in  1Pe 1:8 
between ouk idontes and m(8820)hor(936e)tes. The hireling here is not
necessarily the thief and robber of verses  1,8 . He may
conceivably be a nominal shepherd (pastor) of the flock who
serves only for the money, a sin against which Peter warned the
shepherds of the flock "not for shameful gain" ( 1Pe 5:2 ).
{Whose own} (hou idia). Every true shepherd considers the sheep
in his care "his own" (idia) even if he does not actually "own"
them. The mere "hireling" does not feel so. {Beholdeth}
(	he(9372)ei). Vivid dramatic present, active indicative of
	he(9372)e(935c), a graphic picture. {The wolf coming} (	on lukon
erchomenon). Present middle predicate participle of erchomai.
{Leaveth the sheep, and fleeth} (aphi(8873)in ta probata kai
pheugei). Graphic present actives again of aphi(886d)i and
pheug(935c). The cowardly hireling cares naught for the sheep, but
only for his own skin. The wolf was the chief peril to sheep in
Palestine. See  Mt 10:6  where Jesus says: "Behold I send you
forth as sheep in the midst of wolves." {And the wolf snatcheth
them and scattereth them} (kai ho lukos harpazei kai
skorpizei). Vivid parenthesis in the midst of the picture of the
conduct of the hireling. Bold verbs these. For the old verb
harpaz(935c) see  Joh 6:15  Mt 11:12 , and for skorpiz(935c), late word
(Plutarch) for the Attic skedannumi, see  Mt 12:30 . It occurs
in the vision of Ezekiel ( Eze 34:5 ) where because of the
careless shepherds "the sheep became meat to all the beasts of
the field, and were scattered." Jesus uses harpaz(935c) in  10:29 
where no one is able "to snatch" one out of the Father's hand.
