Exodus 3:1 (ESV)

1 Now Moses was keeping the flock of his father-in-law, Jethro, the priest of Midian, and he led his flock to the west side of the wilderness and came to Horeb, the mountain of God.

Jesus is the good Shepherd who laid down his live for the sheep (John 10:11). He is sent to earth to save God’s people (Matthew 1:21). Elders or overseers in the church have to watch the flock and be shepherds of the church that Jesus bought with his own blood (Acts 20:28). The overseers have to do it willingly, not because they are forced to do it (1 Peter 5:2–4).
