John Chrysostom

(Hom. lix. 3. c. 7, 48.) As they had called Him a deceiver, and appealed to their own unbelief as the proof of it; (Which of the rulers believeth on Him?) He shews here that it was because they refused to hear Him, that they were put out of His flock. The sheep hear His voice. The Shepherd enters by the lawful door; and they who follow Him are His sheep; they who do not, voluntarily put themselves out of His flock.
