Albert Barnes Commentary 1 Samuel 17:52

"And the men of Israel and of Judah arose, and shouted, and pursued the Philistines, until thou comest to Gai, and to the gates of Ekron. And the wounded of the Philistines fell down by the way to Shaaraim, even unto Gath, and unto Ekron." — 1 Samuel 17:52 (ASV)

The men of Israel and Judah - See 1 Samuel 15:4 note.

Shaaraim - A town of Judah in the Shephelah (see the marginal reference), which was probably in the possession of the Philistines at this time.
