1 Samuel 17:32-40

32And David said to Saul, Let no man's heart fail because of him: thy servant will go and fight with this Philistine.

33And Saul said to David, Thou art not able to go against this Philistine to fight with him; for thou art but a youth, and he a man of war from his youth.

34And David said to Saul, Thy servant fed his father's sheep, and there came a lion, and also a bear, and took a lamb out of the flock.

35And I went after him, and smote him, and delivered it out of his mouth; and when he arose against me, I seized him by his beard, and smote him, and slew him.

36Thy servant smote both the lion and the bear; and this uncircumcised Philistine shall be as one of them, because he has defied the armies of the living 1God.

37And David said, Jehovah who delivered me out of the paw of the lion and out of the paw of the bear, he will deliver me out of the hand of this Philistine. And Saul said to David, Go, and Jehovah be with thee.

38And Saul clothed David with his dress, and put a helmet of bronze upon his head, and clothed him with a corselet.

39And David girded his sword upon his dress, and endeavoured to go; for he had not yet tried [it]. And David said to Saul, I cannot go in these; for I have never tried [them]. And David put them off him.

40And he took his staff in his hand, and chose him five smooth stones out of the brook, and put them in the shepherd's bag that he had, into the pocket; and his sling was in his hand. And he drew near to the Philistine.
