The Lord’s sheeps listen to His voice.

Several flocks sometimes allowed to mix. More than one flock may be kept in the same fold, and often flocks are mixed while being watered at a well. For the time being, no attempt is made to separate them. Jacob saw such a mixture of flocks: “Then Jacob went on his journey, and came into the land of the people of the East. And he looked, and behold, a well in the field, and lo, there were three flocks of sheep lying by it” (Gen 29:1-3).18

Ability to separate the sheep. When it becomes necessary to separate several flocks of sheep, one shepherd after another will stand up and call out: “Tahhoo! Tahhoo!” or a similar call of his own choosing. The sheep lift up their heads, and after a general scramble, begin following each one his own shepherd. They are thoroughly familiar with their own shepherd’s tone of voice. Strangers have often used the same call, but their attempts to get the sheep to follow them always fail.19 The words of Jesus are indeed true to Eastern shepherd life when he said: “The sheep follow him, for they know his voice. And a stranger will they not follow, but will flee from him: for they know not the voice of strangers” (Joh 10:4,5).
