John 10:4-5, 16

And when he brings out his own sheep, he goes before them; and the sheep follow him, for they know his voice. Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers.”

And other sheep I have which are not of this fold; them also I must bring, and they will hear My voice; and there will be one flock and one shepherd.
