1 Samuel 17:17-41

Then Jesse said to his son David, “Take now for your brothers an ephah of this roasted grain and these ten loaves, and run to the camp to your brothers. Bring also these ten slices of cheese to the commander of their thousand, and look into the well-being of your brothers and bring back confirmation from them. For Saul and they and all the men of Israel are in the Valley of Elah, fighting the Philistines.” So David got up early in the morning and left the flock with a keeper, and took the supplies and went as Jesse had commanded him. And he came to the entrenchment encircling the camp while the army was going out in battle formation, shouting the war cry. Israel and the Philistines drew up in battle formation, army against army. Then David left the baggage in the care of the baggage keeper and ran to the battle line. And he entered and greeted his brothers. As he was speaking with them, behold, the champion, the Philistine from Gath named Goliath, was coming up from the army of the Philistines, and he spoke these same words; and David heard him. When all the men of Israel saw the man, they fled from him and were very fearful. And the men of Israel said, “Have you seen this man who is coming up? Surely he is coming up to defy Israel. And it will be that the king will make the man who kills him wealthy with great riches, and will give him his daughter and make his father’s house free in Israel.” Then David said to the men who were standing by him, “What will be done for the man who kills this Philistine and rids Israel of the disgrace? For who is this uncircumcised Philistine, that he has dared to defy the armies of the living God?” The people answered him in agreement with this statement, saying, “This is what will be done for the man who kills him.” Now Eliab his oldest brother heard him when he spoke to the men; and Eliab’s anger burned against David and he said, “Why is it that you have come down? And with whom have you left those few sheep in the wilderness? I myself know your insolence and the wickedness of your heart; for you have come down in order to see the battle.” But David said, “What have I done now? Was it not just a question?” Then he turned away from him to another and said the same thing; and the people replied with the same words as before. When the words that David spoke were heard, they informed Saul, and he sent for him. And David said to Saul, “May no one’s heart fail on account of him; your servant will go and fight this Philistine!” But 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.” But 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, I 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. Your 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.” And 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.” Then Saul clothed David with his military attire and put a bronze helmet on his head, and outfitted him with armor. And 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. Then 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. Then the Philistine came and approached David, with the shield-bearer in front of him.
