Passage
Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines.
Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines.
1 Samuel 17:17 Jesse said to David his son, “Now take for your brothers an ephah of this parched grain, and these ten loaves, and carry them quickly to the camp to your brothers;
1 Samuel 17:18 and bring these ten cheeses to the captain of their thousand, and see how your brothers are doing, and bring back news.”
1 Samuel 17:19 Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines.
1 Samuel 17:20 David rose up early in the morning, and left the sheep with a keeper, and took and went, as Jesse had commanded him. He came to the place of the wagons, as the army which was going out to the fight shouted for the battle.
1 Samuel 17:21 Israel and the Philistines put the battle in array, army against army.
The verse centers on "saul", "israel", "valley", "elah", "fighting", and "philistines". It is saying that the verse draws attention to "saul" and "israel", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 18's "and bring these ten cheeses to the..." into verse 20's "David rose up early in the morning...", so "saul" 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 "saul" and "israel" with trust shaped by these words, not by a vague optimism outside the passage.
