“Truly I tell you, anyone who doesn’t enter the sheep pen by the gate but climbs in some other way is a thief and a robber. The one who enters by the gate is the shepherd of the sheep. The gatekeeper opens it for him, and the sheep hear his voice. He calls his own sheep by name and leads them out. When he has brought all his own outside, he goes ahead of them. The sheep follow him because they know his voice. They will never follow a stranger; instead they will run away from him, because they don’t know the voice of strangers.” Jesus gave them this figure of speech, but they did not understand what he was telling them.
