John 10:1-6

1 "Most assuredly, I say to you, he who does not enter the sheepfold by the door, but climbs up some other way, the same is a thief and a robber.

2 But he who enters by the door is the shepherd of the sheep.

3 To him the doorkeeper opens, and the sheep hear his voice; and he calls his own sheep by name and leads them out.

4 And when he brings out his own sheep, he goes before them; and the sheep follow him, for they know his voice.

5 Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers."

6 Jesus used this illustration, but they did not understand the things which He spoke to them.
