The shepherd is called a watchman for good reason! He can never neglect the safety of his flock, nor be indifferent or reckless concerning their constant need for food and shelter. If he becomes timid and self-preserving, he will run at the first sign of trouble and the sheep are doomed. If he miscalculates the seriousness of his duties and becomes careless or casual, the flock will not be spared.
