"You have made us for yourself
and our heart is restless until it rests in you."
Augustine, 398 CE
The shepherd-poet David describes this God-given rest from anxiety and fear through the metaphor of a sheep quietly grazing under the watchful care of the shepherd.
He makes me lie down in green pastures,
He leads me beside quiet waters,
He restores my soul.
Psalm 23:2-3
Pastures and streams provide the essentials - food and drink - for sheep. After grazing in the meadow sheep lie down to ruminate – their appetite contented and their security protected by the vigilant shepherd. It’s a picture of
shalom.
If the early morning grass is dew-laden, the sheep have no need for streams, but the sun in Palestine can burn off the dew quickly and then sheep need additional water.
The shepherd leads his flock to still waters where it is easy for them to drink. Satisfaction, tranquility, peace.
