{Because he is a hireling} (hoti misth(9374)os estin). And
only that, without the shepherd heart that loves the sheep.
Reason given for the conduct of the hireling after the
parenthesis about the wolf. {And careth not for the sheep} (kai
ou melei aut(9369) peri t(936e) probat(936e)). Literally, "and it is no care
to him about the sheep." This use of the impersonal melei
(present active indicative) is quite common, as in  Mt 22:16 .
But God does care ( 1Pe 5:7 ).
