I am the good shepherd: the good shepherd gives his life for the sheep.
All Commentaries on John 10:11 Go To John 10
The Apostolic Constitutions
AD 375
For "the good shepherd lays down his life for the sheep; but he that is an hireling, and not the shepherd, whose own the sheep are not, seeth the wolf coming, that is, the devil, and he leaveth the sheep, and fleeth, and the wolf seizes upon them."
