A.T. Robertson Commentary John 10:14

"I am the good shepherd; and I know mine own, and mine own know me," — John 10:14 (ASV)

I am the good-shepherd (εγω ειμ ο ποιμην ο καλος). Effective repetition.

And mine own know me (κα γινωσκουσιν με τα εμα). Jesus as the Good Shepherd knows his sheep by name as he had already said (verse 3) and now repeats. Yes, and they know his voice (verse 4), they have experimental knowledge (γινωσκω) of Jesus as their own Shepherd. Here (in this mutually reciprocal knowledge) lies the secret of their love and loyalty.
