David vs Goliath: The Journey In Faith and Courage.

The least of you will become a thousand, I will accomplish it quickly in its time and the smallest a mighty nation. I am the LORD, then all your people will be righteous; they will possess the land forever; they are the branch of My planting, the work of My hands, so that I may be glorified. The words that David said were overheard and reported before Saul. So, he was taken to him. David said to Saul, “Let no one’s heart fail because of him. Your servant will go and fight with this Philistine.” Then Saul said to David, “You can’t go fight this Philistine-for you’re just a youth, and he’s been a warrior since his youth.” But David said to Saul, “Your servant has been tending his father’s sheep. When a lion or a bear came and carried off a lamb out of the flock, I went out after it, struck it down, and rescued the lamb out of its mouth. If it rose up against me, I grabbed him by its fur, struck it and killed it. Your servant has killed both the lion and the bear, so this uncircumcised Philistine will become like one of them-since he has defied the ranks of the living God.” Then David said, “Adonai, who has delivered me from the paw of the lion and from the paw of the bear, will deliver me from the hand of this Philistine.” “Go!” said Saul to David, “and may Adonai be with you.” Then Saul clothed David with his own garb, put a bronze helmet on his head, and clothed him in armor. David strapped his sword on his garment and tried to walk, but he was not used to it. So, David said to Saul, “I cannot walk in these, for I am not used to them.” So, David took them off. Then he took his staff in his hand, chose five smooth stones from the valley, put them in the pocket of the shepherd’s bag that he had, and with his sling in his hand, he approached the Philistine. Meanwhile, the Philistine drew nearer and approached David, with his shield-bearer in front of him. Now when the Philistine looked and saw David, he disdained him, for he was just a ruddy boy with a handsome appearance. Then the Philistine said to David, “Am I a dog, that you come to me with sticks?” Then the Philistine cursed David by his gods. The Philistine said to David, “Come to me, so I may give your flesh to the birds of the sky and the beasts of the field.” Then David said to the Philistine, “You are coming to me with a sword, a spear and a javelin, but I am coming to you in the Name of Adonai-Tzva’ot, God of the armies of Israel, whom you have defied. This very day Adonai will deliver you into my hand, and I will strike you down and take your head off you, and I will give the carcasses of the Philistines’ camp today to the birds of the sky and the wild beasts of the earth. Then all the earth will know that there is a God in Israel, for the battle belongs to Adonai and so all this assembly will know that Adonai delivers not with sword and spear, and He will give you into our hands.” Then when the Philistine rose and began to advance, drawing near to meet David, David ran quickly toward the battle line to meet the Philistine. David put his hand in his bag, took a stone from it and slung it, striking the Philistine on his forehead. The stone sank into his forehead, so that he fell on his face to the ground. So, David prevailed over the Philistine with a sling and a stone, struck the Philistine down and killed him. Since there was no sword in David’s hand, David ran, stood over the Philistine, picked up his sword, drew it from its sheath, slew him and cut off his head with it. When the Philistines saw that their champion was dead, they fled. Then the men of Israel and Judah rose up, shouted and pursued the Philistines all the way to the valley up to the gates of Ekron. The slain Philistines fell down along the way to Shaaraim, even up to Gath and Ekron. When Bnei-Yisrael returned from chasing the Philistines, they plundered their camp. David took the head of the Philistine and brought it to Jerusalem, but he put his armor in his own tent. Now when Saul saw David going out against the Philistine, he asked Abner, the commander of the army, “Abner, whose son is this boy?” Abner said, “As your soul lives, your majesty, I don’t know.” So, the king said, “Then, find out whose son this young man is.” So, when David returned from killing the Philistine, Abner took him and brought him before Saul with the head of the Philistine in his hand. “Whose son are you, young man?” Saul said to him. David answered, “I am the son of your servant Jesse the Beth-lehemite.”
