1 Samuel 17:32-40

32And David said to Saul, “1May no one’s heart fail on account of him; 2your servant will go and fight this Philistine!” 33But Saul said to David, “3You are not able to go against this Philistine to fight him; for you are only a youth, while he has been a warrior since his youth.” 34But David said to Saul, “Your servant was tending his father’s sheep. When a lion or a bear came and took a sheep from the flock, 35I went out after it and 4attacked it, and 5rescued the sheep from its mouth; and when it rose up against me, I grabbed it by its mane and struck it and killed it. 36Your servant has 6killed both the lion and the bear; and this uncircumcised Philistine will be like one of them, since he has defied the armies of the living God.” 37And David said, “7The Lord who saved me from the paw of the lion and the paw of the bear, He will save me from the hand of this Philistine.” So Saul said to David, “8Go, and may the Lord be with you.” 38Then Saul clothed David with his military attire and put a bronze helmet on his head, and outfitted him with armor. 39And David strapped on his sword over his military attire and struggled at walking, for he had not trained with the armor. So David said to Saul, “I cannot go with these, because I have not trained with them.” And David took them 9off. 40Then he took his staff in his hand and chose for himself five smooth stones from the brook, and put them in the shepherd’s bag which he had, that is, in his shepherd’s pouch, and 10his sling was in his hand; and he approached the Philistine.
