and David saith unto Saul, `Let no man's heart fall because of him, thy servant doth go, and hath fought with this Philistine.'
1 Samuel 17:30 And he turneth round from him unto another, and saith according to this word, and the people return him word as the first word.

1 Samuel 17:32 and David saith unto Saul, `Let no man's heart fall because of him, thy servant doth go, and hath fought with this Philistine.'

1 Samuel 17:34 And David saith unto Saul, `A shepherd hath thy servant been to his father among the sheep, and the lion hath come--and the bear--and hath taken away a sheep out of the drove,
The verse centers on "david", "saith", "saul", "man's", "heart", "fall", "servant", and "doth". It is saying that the verse draws attention to "david" and "saith", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 31's "And the words which David hath spoken..." into verse 33's "And Saul saith unto David Thou art...", so "david" 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 "david" and "saith" with trust shaped by these words, not by a vague optimism outside the passage.
