This verse is describing the selection of Saul as the first king of Israel. Let's break it down:

"They ran and got him there." This indicates that Saul wasn't initially present or pushing himself forward for the kingship. He might have been reluctant or even hiding. This highlights that his selection was based on divine choice rather than self-promotion.

"When he stood among the people, he was higher than any of the people from his shoulders and upward." This verse emphasizes Saul's physical stature. He was significantly taller than everyone else. In ancient cultures, physical appearance, especially height and strength, were often associated with leadership qualities, courage, and divine favor. Saul's height was likely interpreted as a sign of God's blessing and suitability for the role of king. It provided a visible and immediate confirmation of God's choice to the people. This physical attribute set him apart and made him a natural leader in the eyes of the people.

In summary, the verse means that Saul was chosen as king by God, and his remarkable height served as a visible sign of his suitability for the position, reinforcing the idea that he was divinely appointed and fit to lead. It's important to note that while physical appearance played a role in the perception of leadership at the time, true leadership requires more than just physical attributes, as Saul's later story demonstrates.
