John Gill Commentary 1 Samuel 20:38

"And Jonathan cried after the lad, Make speed, haste, stay not. And Jonathan`s lad gathered up the arrows, and came to his master." — 1 Samuel 20:38 (ASV)

And Jonathan cried after the lad, make speed, haste, stay
not
But bring the arrows to him directly, that he might dismiss him; for, observing that no man was passing by, he was desirous of embracing the opportunity for a few minutes to have an interview with David alone before he fled:

and Jonathan's lad gathered up the arrows ;
for though the textual reading is singular, the marginal is plural, to show, as Kimchi observes, that he cast three arrows, as he said he would, (1 Samuel 20:20) ;

and came to his master ;
with them.
