The contrasts between Saul and David appear throughout 1 Samuel. Here are just a few of them to consider along the way.
|Patronym||Son of Kish||Son of Jesse|
|Description||…a handsome young man. There was not a man among the people of Israel more handsome than he. From his shoulders upward he was taller than any of the people.||Now he was ruddy and had beautiful eyes and was handsome.|
|Herding||Lost Donkeys||Contented Sheep|
|Found||Wandering through Ephraim, Benjamin and Zuph||In his father’s fields, tending the flock|
|The Feasts||Public in Mizpah||Public in Bethlehem, but David does not attend|
|Relationship to Samuel||YHWH sends him to Samuel||Samuel goes to him|
|Anointed||Alone, outside of town||In front of his family, in town|
|After his anointing||The Spirit comes upon him||He plays for Saul, because the Spirit has left him|
Of course, I’m only one reader but it does seem rather strange that this many things appear in both narratives. It only makes sense that it is an intentional device meant to contrast the two kings and show the clear superiority of David.
