David [the youngest] went. . . to feed his father’s sheep.
The great men of the Old Testament began their “careers” as shepherds. The Lord, in John’s gospel, commissioned Peter to shepherd the lambs and the sheep. Paul tells the elders of Ephesus to take heed to the flock. Peter exhorts the “elders” to feed the flock of God. What does all this mean? Shepherding is a great work. It’s probably always done behind the scenes but it’s VERY important.
