 Most assuredly, I say to you, he who does not enter the sheepfold by the door but climbs up some other way, the same as a thief and a robber, but he who enters by the door is the shepherd of the sheep. To him the doorkeeper opens, and the sheep hear his voice, and he calls his own sheep by name and leads them out. And when he brings out his own sheep, he goes before them, and the sheep follow him because they know his voice."
