John Lightfoot on John 10:13

[The hireling fleeth.] The Rabbins suppose that some such thing may be done by the hireling, when they allot a mulct, if a sheep should happen to perish through the neglect of its keeper.

"How far is the keeper for hire bound to watch his flock? Till he can say truly, 'In the day the drought consumed me, and the frost by night.'"

"But if, whilst he is going to the city or any ways absent, the wolf or the lion should come and tear the flock, what then?....He ought to have met them with shepherds and clubs," and not to have fled.
