Now David came to Nob, to Ahimelech the priest. And Ahimelech was afraid when he met David, and said to him, “Why are you alone, and no one is with you?” So David said to Ahimelech the priest, “The king has ordered me on some business, and said to me, ‘Do not let anyone know anything about the business on which I send you, or what I have commanded you.’ And I have directed my young men to such and such a place. Now therefore, what have you on hand? Give me five loaves of bread in my hand, or whatever can be found.” And the priest answered David and said, “ There is no common bread on hand; but there is holy bread, if the young men have at least kept themselves from women.” Then David answered the priest, and said to him, “Truly, women have been kept from us about three days since I came out. And the vessels of the young men are holy, and the bread is in effect common, even though it was consecrated in the vessel this day.” So the priest gave him holy bread; for there was no bread there but the showbread which had been taken from before the Lord , in order to put hot bread in its place on the day when it was taken away. Now a certain man of the servants of Saul was there that day, detained before the Lord . And his name was Doeg, an Edomite, the chief of the herdsmen who belonged to Saul. And David said to Ahimelech, “Is there not here on hand a spear or a sword? For I have brought neither my sword nor my weapons with me, because the king’s business required haste.” So the priest said, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, there it is, wrapped in a cloth behind the ephod. If you will take that, take it. For there is no other except that one here.” And David said, “ There is none like it; give it to me.” Then David arose and fled that day from before Saul, and went to Achish the king of Gath.
I Samuel 21:1-10 NKJV
When Saul heard that David and the men who were with him had been discovered—now Saul was staying in Gibeah under a tamarisk tree in Ramah, with his spear in his hand, and all his servants standing about him— then Saul said to his servants who stood about him, “Hear now, you Benjamites! Will the son of Jesse give every one of you fields and vineyards, and make you all captains of thousands and captains of hundreds? All of you have conspired against me, and there is no one who reveals to me that my son has made a covenant with the son of Jesse; and there is not one of you who is sorry for me or reveals to me that my son has stirred up my servant against me, to lie in wait, as it is this day.” Then answered Doeg the Edomite, who was set over the servants of Saul, and said, “I saw the son of Jesse going to Nob, to Ahimelech the son of Ahitub. And he inquired of the Lord for him, gave him provisions, and gave him the sword of Goliath the Philistine.” So the king sent to call Ahimelech the priest, the son of Ahitub, and all his father’s house, the priests who were in Nob. And they all came to the king. And Saul said, “Hear now, son of Ahitub!” He answered, “Here I am, my Lord.” Then Saul said to him, “Why have you conspired against me, you and the son of Jesse, in that you have given him bread and a sword, and have inquired of God for him, that he should rise against me, to lie in wait, as it is this day?” So Ahimelech answered the king and said, “And who among all your servants is as faithful as David, who is the king’s son-in-law, who goes at your bidding, and is honorable in your house? Did I then begin to inquire of God for him? Far be it from me! Let not the king impute anything to his servant, or to any in the house of my father. For your servant knew nothing of all this, little or much.” And the king said, “You shall surely die, Ahimelech, you and all your father’s house!” Then the king said to the guards who stood about him, “Turn and kill the priests of the Lord , because their hand also is with David, and because they knew when he fled and did not tell it to me.” But the servants of the king would not lift their hands to strike the priests of the Lord . And the king said to Doeg, “You turn and kill the priests!” So Doeg the Edomite turned and struck the priests, and killed on that day eighty-five men who wore a linen ephod. Also Nob, the city of the priests, he struck with the edge of the sword, both men and women, children and nursing infants, oxen and donkeys and sheep—with the edge of the sword. Now one of the sons of Ahimelech the son of Ahitub, named Abiathar, escaped and fled after David. And Abiathar told David that Saul had killed the Lord ’s priests. So David said to Abiathar, “I knew that day, when Doeg the Edomite was there, that he would surely tell Saul. I have caused the death of all the persons of your father’s house. Stay with me; do not fear. For he who seeks my life seeks your life, but with me you shall be safe.”
I Samuel 22:6-23 NKJV
Now the Philistines gathered their armies together to battle, and were gathered at Sochoh, which belongs to Judah; they encamped between Sochoh and Azekah, in Ephes Dammim. And Saul and the men of Israel were gathered together, and they encamped in the Valley of Elah, and drew up in battle array against the Philistines. The Philistines stood on a mountain on one side, and Israel stood on a mountain on the other side, with a valley between them. And a champion went out from the camp of the Philistines, named Goliath, from Gath, whose height was six cubits and a span. He had a bronze helmet on his head, and he was armed with a coat of mail, and the weight of the coat was five thousand shekels of bronze. And he had bronze armor on his legs and a bronze javelin between his shoulders. Now the staff of his spear was like a weaver’s beam, and his iron spearhead weighed six hundred shekels; and a shield-bearer went before him. Then he stood and cried out to the armies of Israel, and said to them, “Why have you come out to line up for battle? Am I not a Philistine, and you the servants of Saul? Choose a man for yourselves, and let him come down to me. If he is able to fight with me and kill me, then we will be your servants. But if I prevail against him and kill him, then you shall be our servants and serve us.” And the Philistine said, “I defy the armies of Israel this day; give me a man, that we may fight together.” When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid. Now David was the son of that Ephrathite of Bethlehem Judah, whose name was Jesse, and who had eight sons. And the man was old, advanced in years, in the days of Saul. The three oldest sons of Jesse had gone to follow Saul to the battle. The names of his three sons who went to the battle were Eliab the firstborn, next to him Abinadab, and the third Shammah. David was the youngest. And the three oldest followed Saul. But David occasionally went and returned from Saul to feed his father’s sheep at Bethlehem. And the Philistine drew near and presented himself forty days, morning and evening. Then Jesse said to his son David, “Take now for your brothers an ephah of this dried grain and these ten loaves, and run to your brothers at the camp. And carry these ten cheeses to the captain of their thousand, and see how your brothers fare, and bring back news of them.” Now Saul and they and all the men of Israel were in the Valley of Elah, fighting with the Philistines. So David rose early in the morning, left the sheep with a keeper, and took the things and went as Jesse had commanded him. And he came to the camp as the army was going out to the fight and shouting for the battle. For Israel and the Philistines had drawn up in battle array, army against army. And David left his supplies in the hand of the supply keeper, ran to the army, and came and greeted his brothers. Then as he talked with them, there was the champion, the Philistine of Gath, Goliath by name, coming up from the armies of the Philistines; and he spoke according to the same words. So David heard them. And all the men of Israel, when they saw the man, fled from him and were dreadfully afraid. So the men of Israel said, “Have you seen this man who has come up? Surely he has come up to defy Israel; and it shall be that the man who kills him the king will enrich with great riches, will give him his daughter, and give his father’s house exemption from taxes in Israel.” Then David spoke to the men who stood by him, saying, “What shall be done for the man who kills this Philistine and takes away the reproach from Israel? For who is this uncircumcised Philistine, that he should defy the armies of the living God?” And the people answered him in this manner, saying, “So shall it be done for the man who kills him.” Now Eliab his oldest brother heard when he spoke to the men; and Eliab’s anger was aroused against David, and he said, “Why did you come down here? And with whom have you left those few sheep in the wilderness? I know your pride and the insolence of your heart, for you have come down to see the battle.” And David said, “What have I done now? Is there not a cause?” Then he turned from him toward another and said the same thing; and these people answered him as the first ones did. Now when the words which David spoke were heard, they reported them to Saul; and he sent for him. Then David said to Saul, “Let no man’s heart fail because of him; your servant will go and fight with this Philistine.” And Saul said to David, “You are not able to go against this Philistine to fight with him; for you are a youth, and he a man of war from his youth.” But David said to Saul, “Your servant used to keep his father’s sheep, and when a lion or a bear came and took a lamb out of the flock, I went out after it and struck it, and delivered the lamb from its mouth; and when it arose against me, I caught it by its beard, and struck and killed it. Your servant has killed both lion and bear; and this uncircumcised Philistine will be like one of them, seeing he has defied the armies of the living God.” Moreover David said, “The Lord , who delivered me from the paw of the lion and from the paw of the bear, He will deliver me from the hand of this Philistine.” And Saul said to David, “Go, and the Lord be with you!” So Saul clothed David with his armor, and he put a bronze helmet on his head; he also clothed him with a coat of mail. David fastened his sword to his armor and tried to walk, for he had not tested them. And David said to Saul, “I cannot walk with these, for I have not tested them. ” So David took them off. Then he took his staff in his hand; and he chose for himself five smooth stones from the brook, and put them in a shepherd’s bag, in a pouch which he had, and his sling was in his hand. And he drew near to the Philistine. So the Philistine came, and began drawing near to David, and the man who bore the shield went before him. And when the Philistine looked about and saw David, he disdained him; for he was only a youth, ruddy and good-looking. So the Philistine said to David, “ Am I a dog, that you come to me with sticks?” And the Philistine cursed David by his gods. And the Philistine said to David, “Come to me, and I will give your flesh to the birds of the air and the beasts of the field!” Then David said to the Philistine, “You come to me with a sword, with a spear, and with a javelin. But I come to you in the name of the Lord of hosts, the God of the armies of Israel, whom you have defied. This day the Lord will deliver you into my hand, and I will strike you and take your head from you. And this day I will give the carcasses of the camp of the Philistines to the birds of the air and the wild beasts of the earth, that all the earth may know that there is a God in Israel. Then all this assembly shall know that the Lord does not save with sword and spear; for the battle is the Lord ’s, and He will give you into our hands.” So it was, when the Philistine arose and came and drew near to meet David, that David hurried and ran toward the army to meet the Philistine. Then David put his hand in his bag and took out a stone; and he slung it and struck the Philistine in his forehead, so that the stone sank into his forehead, and he fell on his face to the earth. So David prevailed over the Philistine with a sling and a stone, and struck the Philistine and killed him. But there was no sword in the hand of David. Therefore David ran and stood over the Philistine, took his sword and drew it out of its sheath and killed him, and cut off his head with it. And when the Philistines saw that their champion was dead, they fled. Now the men of Israel and Judah arose and shouted, and pursued the Philistines as far as the entrance of the valley and to the gates of Ekron. And the wounded of the Philistines fell along the road to Shaaraim, even as far as Gath and Ekron. Then the children of Israel returned from chasing the Philistines, and they plundered their tents. And David took the head of the Philistine and brought it to Jerusalem, but he put his armor in his tent. I Samuel 17:1-54 NKJV
