10:1 A wilderness shepherd would build a sheepfold, a pen with low stone walls topped by thorny branches, to hold his sheep at night and protect them from danger. • The pen had one gate (or opening in the wall) that was closed with branches. Any invasion of the pen was a threat to the flock. • A bad shepherd was like a thief and a robber. He exploited the sheep for his own interests and did not care for or nurture them. Bad shepherds took the sheep’s milk and wool for themselves and butchered the sheep without providing for the animal’s safety (Ezek 34:3; see Isa 56:11; Jer 23:1-4). This was Jesus’ most stinging indictment of the Jewish leaders.

10:11-13 Small villages often created communal flocks and employed a hired hand to tend the sheep. However, an employee lacked the commitment of a true shepherd. The wilderness of Judea had many predators. When a wolf or other predators attacked, the hired hand would run rather than defend the sheep. Jesus will never do this; he will always stand between his sheep and danger.

10:11-14 I am: See study note on 6:35. The good shepherd leads his sheep, finds food and water, and locates paths in the wilderness (see Ps 23). The good shepherd stands between his sheep and danger (John 10:11) and fights to protect them. The Old Testament describes God as Israel’s shepherd (Pss 23; 80:1; Isa 40:10-11). The leaders of God’s people should shepherd their flock as God does (Ezek 34:23). However, the leaders of Israel in Jesus’ time were bad shepherds.
