John 10:3-5

Revised Standard Version Catholic Edition

³ To him the gatekeeper opens; the sheep hear his voice, and he calls his own sheep by name and leads them out. ⁴ When he has brought out all his own, he goes before them, and the sheep follow him, for they know his voice. ⁵ A stranger they will not follow, but they will flee from him, for they do not know the voice of strangers.”
