1 Samuel 17:33-45

³³But Saul said to David, “You 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 attacked it, and rescued 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 killed 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, “The 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, “Go, 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 off. 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 his sling was in his hand; and he approached the Philistine.

⁴¹Then the Philistine came and approached David, with the shield-bearer in front of him. ⁴²When the Philistine looked and saw David, he was contemptuous of him; for he was only a youth, and reddish, with a handsome appearance. ⁴³So the Philistine said to David, “Am I a dog, that you come to me with sticks?” And the Philistine cursed David by his gods. ⁴⁴The Philistine also said to David, “Come to me, and I will give your flesh to the birds of the sky and the wild animals.” ⁴⁵But David said to the Philistine, “You come to me with a sword, a spear, and a saber, but I come to you in the name of the Lord of armies, the God of the armies of Israel, whom you have defied.
