john 10:12 But he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, and leaveth the sheep, and fleeth: and the wolf catcheth them, and scattereth the sheep. - Free Bible Online

      12. an hireling . . . whose own the sheep are not--who has no property, in them. By this He points to His own peculiar relation to the sheep, the same as His Father's, the great Proprietor and Lord of the flock, who styles Him "My Shepherd, the Man that is My Fellow" (Zec 13:7), and though faithful under-shepherds are so in their Master's interest, that they feel a measure of His own concern for their charge, the language is strictly applicable only to "the Son over His own house" (Heb 3:6).
      seeth the wolf coming--not the devil distinctively, as some take it [STIER, ALFORD, &c.], but generally whoever comes upon the flock with hostile intent, in whatever form: though the wicked one, no doubt, is at the bottom of such movements [LUTHARDT].
