171 Now the Philistines gathered their armies for battle; they were gathered at Socoh, which belongs to Judah, and encamped between Socoh and Azekah, in Ephes-dammim. 2 Saul and the Israelites gathered and encamped in the valley of Elah, and formed ranks against the Philistines. 3 The Philistines stood on the mountain on the one side, and Israel stood on the mountain on the other side, with a valley between them. 4 And there came out from the camp of the Philistines a champion named Goliath, of Gath, whose height was six cubits and a span. 5 He had a helmet of bronze on his head, and he was armed with a coat of mail; the weight of the coat was five thousand shekels of bronze. 6 He had greaves of bronze on his legs and a javelin of bronze slung between his shoulders. 7 The shaft of his spear was like a weaver's beam, and his spear's head weighed six hundred shekels of iron; and his shield-bearer went before him. 8 He stood and shouted to the ranks of Israel, "Why have you come out to draw up for battle? Am I not a Philistine, and are you not servants of Saul? Choose a man for yourselves, and let him come down to me. 9 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." 10 And the Philistine said, "Today I defy the ranks of Israel! Give me a man, that we may fight together." 11 When Saul and all Israel heard these words of the Philistine, they were dismayed and greatly afraid.
12 Now David was the son of an Ephrathite of Bethlehem in Judah, named Jesse, who had eight sons. In the days of Saul the man was already old and advanced in years. 13 The three eldest sons of Jesse had followed Saul to the battle; the names of his three sons who went to the battle were Eliab the firstborn, and next to him Abinadab, and the third Shammah. 14 David was the youngest; the three eldest followed Saul, 15 but David went back and forth from Saul to feed his father's sheep at Bethlehem. 16 For forty days the Philistine came forward and took his stand, morning and evening. 17 Jesse said to his son David, "Take for your brothers an ephah of this parched grain and these ten loaves, and carry them quickly to the camp to your brothers; 18 also take these ten cheeses to the commander of their thousand. See how your brothers fare, and bring some token from them." 19 Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines. 20 David rose early in the morning, left the sheep with a keeper, took the provisions, and went as Jesse had commanded him. He came to the encampment as the army was going forth to the battle line, shouting the war cry. 21 Israel and the Philistines drew up for battle, army against army. 22 David left the things in charge of the keeper of the baggage, ran to the ranks, and went and greeted his brothers. 23 As he talked with them, the champion, the Philistine of Gath, Goliath by name, came up out of the ranks of the Philistines, and spoke the same words as before. And David heard him. 24 All the Israelites, when they saw the man, fled from him and were very much afraid. 25 The Israelites said, "Have you seen this man who has come up? Surely he has come up to defy Israel. The king will greatly enrich the man who kills him, and will give him his daughter and make his family free in Israel." 26 David said to the men who stood by him, "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?" 27 The people answered him in the same way, "So shall it be done for the man who kills him." 28 His eldest brother Eliab heard him talking to the men; and Eliab's anger was kindled against David. He said, "Why have you come down? With whom have you left those few sheep in the wilderness? I know your presumption and the evil of your heart; for you have come down just to see the battle."

(Read 1 Samuel 17:1-11)
Men so entirely depend upon God in all things, that when he withdraws his help, the most valiant and resolute cannot find their hearts or hands, as daily experience shows.
Commentary on 1 Samuel 17:12-30
(Read 1 Samuel 17:12-30)
Jesse little thought of sending his son to the army at that critical juncture; but the wise God orders actions and affairs, so as to serve his designs. In times of general formality and lukewarmness, every degree of zeal which implies readiness to go further, or to venture more in the cause of God than others, will be blamed as pride and ambition, and by none more than by near relations, like Eliab, or negligent superiors. It was a trial of David's meekness, patience, and constancy. He had right and reason on his side, and did not render railing for railing; with a soft answer he turned away his brother's wrath. This conquest of his own passion was more honourable than that of Goliath. Those who undertake great and public services, must not think it strange if they are spoken ill of, and opposed by those from whom they expect support and assistance. They must humbly go on with their work, in the face not only of enemies' threats, but of friends' slights and suspicions.
