The man who goes in through the gate is the shepherd of the sheep. The gatekeeper opens the gate for him; the sheep hear his voice as he calls his own sheep by name, and he leads them out. When he has brought them out, he goes ahead of them, and the sheep follow him, because they know his voice. They will not follow someone else; instead, they will run away from such a person, because they do not know his voice.”
John 10:2–5
