Passage
And Saul cometh in unto a city of Amalek, and layeth wait in a valley;
And Saul cometh in unto a city of Amalek, and layeth wait in a valley;
1 Samuel 15:3 Now, go, and thou hast smitten Amalek, and devoted all that it hath, and thou hast no pity on it, and hast put to death from man unto woman, from infant unto suckling, from ox unto sheep, from camel unto ass.'
1 Samuel 15:4 And Saul summoneth the people, and inspecteth them in Telaim, two hundred thousand footmen, and ten thousand <FI>are<Fi> men of Judah.
1 Samuel 15:5 And Saul cometh in unto a city of Amalek, and layeth wait in a valley;
1 Samuel 15:6 and Saul saith unto the Kenite, `Go, turn aside, go down from the midst of Amalek, lest I consume thee with it, and thou didst kindness with all the sons of Israel, in their going up out of Egypt;' and the Kenite turneth aside from the midst of Amalek.
1 Samuel 15:7 And Saul smiteth Amalek from Havilah--thy going in to Shur, which <FI>is<Fi> on the front of Egypt,
The verse centers on "saul", "cometh", "city", "amalek", "layeth", "wait", and "valley". It is saying that the verse draws attention to "saul" and "cometh", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 4's "And Saul summoneth the people and inspecteth..." into verse 6's "and Saul saith unto the Kenite Go...", so "saul" and "cometh" 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 "cometh" with trust shaped by these words, not by a vague optimism outside the passage.
