No one would dispute the fact that these beautiful words have a deeper meaning. Obviously, we are not literally sheep, and the Lord is not literally a shepherd. But this is not just poetry; the words have a specific spiritual meaning.

According to the Writings, a shepherd represents someone who teaches people what they need to know to live a good life, and leads them toward that life. To "want" for something means that you lack the knowledge and the inspiration you need to live that good life.

What this verse means, then, is that if we turn to the Lord for knowledge, guidance and leadership, we will get what we need to lead a good life.

(References: Apocalypse Explained 375 [34])

Shepherds represent people who lead and teach others, using knowledge and true ideas to help people reach the goodness of life. This makes sense if you think about what a shepherd does. He makes sure the flock has good grass to eat; plants in the Bible represent facts and knowledge. The shepherd makes sure the flock has good water to drink; water represents true thinking about the spiritual aspect of day-to-day life. He carries weapons (a true understanding of spiritual things) to ward off predators (desires for evil) and keeps the flock safe. And the ultimate goal of the shepherd is for the flock to be useful, to do good, to provide good things, representing the good of life. There are, of course, a few cases in which shepherds are the bad guys (for instance, a group of them in Midian would chase Jethro's daughters away so they could water their sheep first; Moses found favor by helping the daughters and ended up marrying one of them). In these cases shepherds represent people who lead and teach without the good of life as the goal. When goodness is not the goal, ideas and knowledge are twisted into falsity and the teaching and leading trend toward evil. See also Sheep.
