Theophylact of Ohrid

I am the good shepherd, and know my sheep, and am known of mine. As the Father knoweth me, even so know I the Father: and I lay down my life for the sheep. And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd. Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again. This commandment have I received of my Father. There was a division therefore again among the Jews for these sayings. And many of them said, He hath a devil, and is mad; why hear ye him? Others said, These are not the words of him that hath a devil. Can a devil open the eyes of the blind?
