And the men of Israel and Juda rising up shouted, and pursued after the Philistines till they came to the valley and to the gates of Accaron, and there fell many wounded of the Philistines in the way of Saraim, and as far as Geth, and as far as Accaron.
1 Samuel 17:50 And David prevailed over the Philistine, with a sling and a stone, and he struck, and slew the Philistine. And as David had no sword in his hand,
1 Samuel 17:51 He ran, and stood over the Philistine, and took his sword, and drew it out of the sheath, and slew him, and cut off his head. And the Philistines seeing that their champion was dead, fled away.
1 Samuel 17:52 And the men of Israel and Juda rising up shouted, and pursued after the Philistines till they came to the valley and to the gates of Accaron, and there fell many wounded of the Philistines in the way of Saraim, and as far as Geth, and as far as Accaron.
1 Samuel 17:53 And the children of Israel returning, after they had pursued the Philistines, fell upon their camp.
1 Samuel 17:54 And David taking the head of the Philistine, brought it to Jerusalem: but his armour he put in his tent.
The verse centers on "wounded", "israel", "juda", "rising", "shouted", "pursued", "after", and "philistines". It is saying that the verse draws attention to "wounded" and "israel", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 51's "He ran and stood over the Philistine..." into verse 53's "And the children of Israel returning after...", so "wounded" and "israel" belong inside that flow. In 1 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "wounded" and "israel" with trust shaped by these words, not by a vague optimism outside the passage.
