1st Samuel 17:41

38 Then Saul gave David his clothing of war, and put a head-dress of brass on his head and had him clothed with a coat of metal.

39 And David took Saul's sword and put the band round him over the metal coat, and was unable to go forward; for he was not used to them. Then David said to Saul, It is not possible for me to go out with these, for I am not used to them. So David took them off.

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.

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.
