John 10:14 - Ellicott's Commentary On The Whole Bible

And know my sheep, and am known of mine. — Better, and know those who are Mine, and those who are Mine know Me. The thought of the Good Shepherd is repeated to show that it expresses the closest communion between the shepherd and the sheep. It is not simply that the sheep know the Shepherd’s voice, but they partake of His nature, and the solemn form in which He expresses this union is in likening it to that between His Father and Himself.
