John Gill Commentary 1 Samuel 10:23

"And they ran and fetched him thence; and when he stood among the people, he was higher than any of the people from his shoulders and upward." — 1 Samuel 10:23 (ASV)

And they ran and fetched him from there
Being in haste to see their king elect, and proclaim him:

and when he stood among the people ;
being brought among them, and presented to them:

he was higher than any of the people, from the shoulders, and upwards ;
which made him look very graceful and majestic; height of stature, and a comely form, as Kimchi observes, recommend to royal dignity; and make the people stand more in awe of a prince, and have always been reckoned among all other nations to make a prince venerable, (See Gill on 1 Samuel 9:2).
