This famous Old Testament passage such as this, with its powerful shepherd imagery, propels us to the New Testament—specifically to John 10. Jesus is the Good Shepherd, who showed us the way through the valley of the shadow of death. By suffering death on the cross for our sins, he has opened the way for us to come into his pasture, if we trust in him for the forgiveness of our sin. All that David expresses about the shepherd in Psalm 23, Jesus has done for us as the Good Shepherd.
