1 Peter 5:1-4
1So I exhort the elders among you, as a fellow elder and a witness of the sufferings of Christ, as well as a partaker in the glory that is going to be revealed: 2shepherd the flock of God that is among you, exercising oversight,a not under compulsion, but willingly, as God would have you;bnot for shameful gain, but eagerly; 3not domineering over those in your charge, but being examples to the flock. 4And when the chief Shepherd appears, you will receive the unfading crown of glory.
Acts 20:28-32
28Pay careful attention to yourselves and to all the flock, in which the Holy Spirit has made you overseers, to care for the church of God,e which he obtained with his own blood.f 29I know that after my departure fierce wolves will come in among you, not sparing the flock; 30and from among your own selves will arise men speaking twisted things, to draw away the disciples after them.
John 10:11
I am the good shepherd. The good shepherd lays down his life for the sheep.
