John 10:7; John 10:9; John 10:14

7 Then said Jesus to them again, Verily, verily, I say to you, I am the door of the sheep.
9 I am the door: by me if any man shall enter he shall be saved, and shall go in and out, and find pasture.
14 I am the good shepherd, and know my [sheep], and am known by mine.
