But he that is a hireling, and not the shepherd, whose own the sheep are not, sees the wolf coming, and leaves the sheep, and flees: and the wolf catches them, and scatters the sheep.
All Commentaries on John 10:12 Go To John 10
Tertullian of Carthage
AD 220
But Christ, confirming these foreshadowings Himself, adds: "The bad shepherd is he who, on seeing the wolf, flees, and leaves the sheep to be torn in pieces."
