Passage
And Jehovah saith unto Samuel, `Lo, I am doing a thing in Israel, at which the two ears of every one hearing it do tingle.
And Jehovah saith unto Samuel, `Lo, I am doing a thing in Israel, at which the two ears of every one hearing it do tingle.
1 Samuel 3:9 And Eli saith to Samuel, `Go, lie down, and it hath been, if He doth call unto thee, that thou hast said, Speak, Jehovah, for Thy servant is hearing;' and Samuel goeth and lieth down in his place.
1 Samuel 3:10 And Jehovah cometh, and stationeth Himself, and calleth as time by time, `Samuel, Samuel;' and Samuel saith, `Speak, for Thy servant is hearing.'
1 Samuel 3:11 And Jehovah saith unto Samuel, `Lo, I am doing a thing in Israel, at which the two ears of every one hearing it do tingle.
1 Samuel 3:12 In that day I establish unto Eli all that I have spoken unto his house, beginning and completing;
1 Samuel 3:13 and I have declared to him that I am judging his house--to the age, for the iniquity which he hath known, for his sons are making themselves vile, and he hath not restrained them,
The verse centers on "jehovah", "saith", "samuel", "doing", "israel", "ears", "hearing", and "tingle". It is saying that the verse draws attention to "jehovah" and "saith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 10's "And Jehovah cometh and stationeth Himself and..." into verse 12's "In that day I establish unto Eli...", so "jehovah" and "saith" 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 "jehovah" and "saith" with trust shaped by these words, not by a vague optimism outside the passage.
