Acts 20:28

1 Peter 5:2-3 NIV
Be shepherds of God’s flock that is under your care, watching over them—not because you must, but because you are willing, as God wants you to be; not pursuing dishonest gain, but eager to serve; not lording it over those entrusted to you, but being examples to the flock.

1 Timothy 4:16 NIV
Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.

Isaiah 40:11 NIV
He tends his flock like a shepherd: He gathers the lambs in his arms and carries them close to his heart; he gently leads those that have young.
