He maketh me lie down in green pastures:
He leadeth me beside the still waters.

                                            psalms 23:2

And when he putteth forth his own sheep, 
he goeth forth before them, and the sheep follow him:
for they know his voice.
And a stranger they will not follow,
but will flee from him:
For they know not the voice of strangers.

                                           John 10:4, 5
