17:40 And he took his {n} staff in his hand, and chose him five smooth stones out of the brook, and put them in a shepherd's bag which he had, even in a scrip; and his sling [was] in his hand: and he drew near to the Philistine.
(n) So that by these weak means, It might be known that only God was the author of this victory.
17:40 Staff - His shepherd's staff. These arms in themselves were contemptible, yet chosen by David; because he had no skill to use other arms; because he had inward assurance of the victory, even by these weapons; and because such a conquest would be more honourable to God, and most shameful, and discouraging to the Philistines.
17:40-47 The security and presumption of fools destroy them. Nothing can excel the humility, faith, and piety which appear in David's words. He expressed his assured expectation of success; he gloried in his mean appearance and arms, that the victory might be ascribed to the Lord alone.
