What does the Bible say about shepherds?

In John 10, Jesus famously describes Himself as the Good Shepherd, a title indicating His role in caring for His people. Unlike false shepherds, who are characterized as thieves and robbers, Jesus enters the sheepfold by the door and leads His sheep with love and sacrifice. Throughout scripture, the concept of the shepherd is critical, depicting God's provision and guidance, exemplified by David in Psalm 23, where he states, 'The Lord is my shepherd; I shall not want.' This image implies that true shepherds lead their flock into safety and nourishment, while false shepherds seek their own gain.
