'Shepherd' in the Bible

But he who enters by the door is the shepherd of the sheep [the protector and provider].

I am the Good Shepherd. The Good Shepherd lays down His [own] life for the sheep.

But the hired man [who merely serves for wages], who is neither the shepherd nor the owner of the sheep, when he sees the wolf coming, deserts the flock and runs away; and the wolf snatches the sheep and scatters them.

I am the Good Shepherd, and I know [without any doubt those who are] My own and My own know Me [and have a deep, personal relationship with Me]—

I have other sheep [beside these] that are not of this fold. I must bring those also, and they will listen to My voice and pay attention to My call, and they will become one flock with one Shepherd.

Again He said to him a second time, “Simon, son of John, do you love Me [with total commitment and devotion]?” He said to Him, “Yes, Lord; You know that I love You [with a deep, personal affection, as for a close friend].” Jesus said to him, “Shepherd My sheep.”
