Study Lenses
The verse centers on "declareth", "heart", "saith", "razor", "hath", "gone", "head", and "nazarite". It is saying that the verse draws attention to "declareth" and "heart", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 16's "And it cometh to pass because she..." into verse 18's "And Delilah seeth that he hath declared...", so "declareth" and "heart" belong inside that flow. In Judges context, the local focus is covenant, worship, and faithfulness.
A plain takeaway is to answer the verse's own emphasis on "declareth" and "heart" with trust shaped by these words, not by a vague optimism outside the passage.
