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. 44 And the Philistine said to David, Come here to me, and I will give your flesh to the birds of the air and the beasts of the field.

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.
