40 Then he took his stick in his hand, and got five smooth stones from the bed of the stream and put them in a bag such as is used by sheep-keepers; and in his hand was a leather band used for sending stones: and so he went in the direction of the Philistine. 41 And the Philistine came nearer to David; and the man who had his body-cover went before him. 42 And when the Philistine, taking note, saw David, he had a poor opinion of him: for he was only a boy, red-haired and good-looking. 43 And the Philistine said to David, Am I a dog, that you come out to me with sticks? And the Philistine put curses on David by all his gods.

Commentary on 1 Samuel 17:40-47
(Read 1 Samuel 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.
