John 10:2-5

2But the one who enters by the gate is the shepherd of the sheep. 3The gatekeeper opens the gate for him, and the sheep listen for his voice. He calls his own sheep by name and leads them out.

4When he has brought out all his own, he goes on ahead of them, and his sheep follow him because they know his voice. 5But they will never follow a stranger; in fact, they will flee from him because they do not recognize his voice.”
