Albert Barnes Commentary 1 Samuel 7:11

"And the men of Israel went out of Mizpah, and pursued the Philistines, and smote them, until they came under Beth-car." — 1 Samuel 7:11 (ASV)

Beth-car — This place is nowhere else mentioned. It seems to have stood on a hill overhanging the road from the Philistine territory to Mizpeh, and close to Ebenezer (1 Samuel 4:1).
