5 But they will never follow a stranger; in fact, they will run away from him because they do not recognize a stranger’s voice.”
14 “I am the good shepherd; I know my sheep and my sheep know me-15 just as the Father knows me and I know the Father-and I lay down my life for the sheep. 16 I have other sheep that are not of this sheep pen. I must bring them also. They too will listen to my voice, and there shall be one flock and one shepherd.27 My sheep listen to my voice; I know them, and they follow me.
A traveler in the Holy Land tells the story about stopping at a watering place. He saw three shepherds come down to the water with their flocks, a total of about one hundred sheep in all. Soon all three flocks intermingled. An outsider could never tell to which shepherd the sheep belonged. But soon one shepherd walked away a little distance and gave his call. His flock of sheep separated themselves from the others and followed him. They followed the voice of their shepherd but they would not follow a stranger.
