'Shepherd' in the Bible

and he who is entering through the door is shepherd of the sheep;

'I am the good shepherd; the good shepherd his life layeth down for the sheep;

and the hireling, and not being a shepherd, whose own the sheep are not, doth behold the wolf coming, and doth leave the sheep, and doth flee; and the wolf catcheth them, and scattereth the sheep;

I am the good shepherd, and I know my sheep, and am known by mine,

and other sheep I have that are not of this fold, these also it behoveth me to bring, and my voice they will hear, and there shall become one flock -- one shepherd.
