Acts 20:28
So, pay close attention to your [own] lives, and to all [members] of the flock [i.e., the congregation] of which the Holy Spirit has made you overseers [i.e., elders, shepherds or pastors]. Provide [spiritual] food for the church of the Lord which He purchased by [shedding] His own blood.
Hebrews 12:9

1 Peter 5:2-4
You should serve as shepherds of God's flock [i.e., the church], among whom you minister, providing careful oversight [of the people], not because you feel forced to, but because you want to, as this is in accordance with the way God wants it to be. Do not [serve as elders] simply out of a desire for the income you receive, but because your heart is in it.
