John Gill Commentary 1 Samuel 17:41

"And the Philistine came on and drew near unto David; and the man that bare the shield went before him." — 1 Samuel 17:41 (ASV)

And the Philistine came on, and drew near unto David
By slow paces, because of the weight of his armour, and bulk of his body, yet with a haughty air, and a proud gait:

and the man that bore the shield [went] before him ;
(See Gill on 1 Samuel 17:7).
