12 Enter David. He was the son of Jesse the Ephrathite from Bethlehem in Judah. Jesse, the father of eight sons, was himself too old to join Saul's army. 13 Jesse's three older sons had followed Saul to war. The names of the three sons who had joined up with Saul were Eliab, the firstborn; next, Abinadab; and third, Shammah. 14 David was the youngest son. While his three oldest brothers went to war with Saul, David went back and forth from attending to Saul to tending his father's sheep in Bethlehem. 15 16 Each morning and evening for forty days, Goliath took his stand and made his speech. 17 One day, Jesse told David his son, "Take this sack of cracked wheat and these ten loaves of bread and run them down to your brothers in the camp. 18 And take these ten wedges of cheese to the captain of their division. Check in on your brothers to see whether they are getting along all right, and let me know how they're doing 19 - Saul and your brothers, and all the Israelites in their war with the Philistines in the Oak Valley." 20 David was up at the crack of dawn and, having arranged for someone to tend his flock, took the food and was on his way just as Jesse had directed him. He arrived at the camp just as the army was moving into battle formation, shouting the war cry. 21 Israel and the Philistines moved into position, facing each other, battle-ready. 22 David left his bundles of food in the care of a sentry, ran to the troops who were deployed, and greeted his brothers. 23 While they were talking together, the Philistine champion, Goliath of Gath, stepped out from the front lines of the Philistines, and gave his usual challenge. David heard him. 24 The Israelites, to a man, fell back the moment they saw the giant - totally frightened. 25 The talk among the troops was, "Have you ever seen anything like this, this man openly and defiantly challenging Israel? The man who kills the giant will have it made. The king will give him a huge reward, offer his daughter as a bride, and give his entire family a free ride." 26 David, who was talking to the men standing around him, asked, "What's in it for the man who kills that Philistine and gets rid of this ugly blot on Israel's honor? Who does he think he is, anyway, this uncircumcised Philistine, taunting the armies of God-Alive?" 27 They told him what everyone was saying about what the king would do for the man who killed the Philistine. 28 Eliab, his older brother, heard David fraternizing with the men and lost his temper: "What are you doing here! Why aren't you minding your own business, tending that scrawny flock of sheep? I know what you're up to. You've come down here to see the sights, hoping for a ringside seat at a bloody battle!" 29 "What is it with you?" replied David. "All I did was ask a question." 30 Ignoring his brother, he turned to someone else, asked the same question, and got the same answer as before.

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.
