John 10:1-6
1 Verily, verily, I say unto you, He that entereth not by the door into the fold of the sheep, but climbeth up some other way, the same is a thief and a robber.
2 But he that entereth in by the door is the shepherd of the sheep.
3 To him the porter openeth; and the sheep hear his voice: and he calleth his own sheep by name, and leadeth them out.
4 When he hath put forth all his own, he goeth before them, and the sheep follow him: for they know his voice.
5 And a stranger will they not follow, but will flee from him: for they know not the voice of strangers.
6 This parable spake Jesus unto them: but they understood not what things they were which he spake unto them.
