In Palestine today, it is still possible to witness a scene that Jesus almost certainly saw two thousand years ago, that of Bedouin shepherds bringing their flocks home from the various pastures they have grazed during the day. Often those flocks will end up at the same watering hole around dusk, so that they get all mixed up together—eight or nine small flocks turning into a convention of thirsty sheep. Their shepherds do not worry about the mix-up, however. When it is time to go home, each one issues his or her own distinctive call—a special trill or whistle, or a particular tune on a particular reed pipe, and that shepherd's sheep withdraw from the crowd to follow their shepherd home. They know whom they belong to; they know their shepherd's voice, and it is the only one they will follow.
