For you were going astray like sheep; but are now returned to the Shepherd and Overseer{"Overseer" is from the Greek episkopon, which can mean overseer, curator, guardian, or superintendent.} of your souls.
Shepherd -- This title is used of God (cf. Psalms 23:1, Ezekiel 34:1 ff) and here of Jesus as in John 10:1-18 and Hebrews 13:20. It connotes tender, thoughtful, continuous care. This title may even reflect Peter’s discussion with Jesus in John 21 (cf. 1 Peter 5:1-3).
