Passage
And the word of Jehovah came to Samuel, saying,
And the word of Jehovah came to Samuel, saying,
1 Samuel 15:8 And he took Agag the king of Amalek alive, and utterly destroyed all the people with the edge of the sword.
1 Samuel 15:9 And Saul and the people spared Agag, and the best of the sheep and oxen, and beasts of the second bearing, and the lambs, and all that was good, and would not devote them to destruction; but everything that was mean and weak, that they destroyed utterly.
1 Samuel 15:10 And the word of Jehovah came to Samuel, saying,
1 Samuel 15:11 It repenteth me that I have set up Saul to be king; for he is turned away from following me, and hath not fulfilled my words. And Samuel was much grieved; and he cried to Jehovah all night.
1 Samuel 15:12 And Samuel rose early to meet Saul in the morning. And it was told Samuel, saying, Saul came to Carmel, and behold, he set him up a monument, and has turned about, and passed on, and gone down to Gilgal.
The verse centers on "word", "jehovah", "came", "samuel", and "saying". It is saying that the verse draws attention to "word" and "jehovah", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "And Saul and the people spared Agag..." into verse 11's "It repenteth me that I have set...", so "word" and "jehovah" 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 "word" and "jehovah" with trust shaped by these words, not by a vague optimism outside the passage.
