Passage
And Jehovah addeth to appear in Shiloh, for Jehovah hath been revealed unto Samuel, in Shiloh, by the word of Jehovah.
And Jehovah addeth to appear in Shiloh, for Jehovah hath been revealed unto Samuel, in Shiloh, by the word of Jehovah.
1 Samuel 3:19 And Samuel groweth up, and Jehovah hath been with him, and hath not let fall any of his words to the earth;
1 Samuel 3:20 and all Israel know, from Dan even unto Beer-Sheba, that Samuel is established for a prophet to Jehovah.
1 Samuel 3:21 And Jehovah addeth to appear in Shiloh, for Jehovah hath been revealed unto Samuel, in Shiloh, by the word of Jehovah.
The verse centers on "jehovah", "addeth", "appear", "shiloh", "hath", "been", and "revealed". It is saying that the verse draws attention to "jehovah" and "addeth", so its meaning should be read from those terms before moving to application.
The prior verse says "and all Israel know from Dan even...", giving immediate footing for "jehovah" and "addeth". In 1 Samuel context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "jehovah" and "addeth" with trust shaped by these words, not by a vague optimism outside the passage.
