12 Now David was the son of that Ephrathite of Beth-lehem-judah named Jesse, who had eight sons; and he was an old man in Saul's day, and far on in years. 13 And the three oldest sons of Jesse had gone with Saul to the fight: the names of the three who went to the fight were Eliab, the oldest, and Abinadab the second, and Shammah the third. 14 And David was the youngest: and the three oldest were with Saul's army. 15 Now David went to and from Saul, looking after his father's sheep at Beth-lehem. 16 And the Philistine came near every morning and evening for forty days. 17 And Jesse said to his son David, Take now for your brothers an ephah of this dry grain and these ten cakes of bread, and go quickly with them to the tents to your brothers; 18 And take these ten cheeses to the captain of their thousand, and see how your brothers are and come back with a sign to say how they are. 19 Now Saul, and they, and all the men of Israel were in the valley of Elah, fighting with the Philistines. 20 And David got up early in the morning, and, giving the sheep into the care of a keeper, took the things and went as Jesse had said; and he came to the lines where the carts were, when the army was going out to the fight giving their war-cry. 21 And Israel and the Philistines had put their forces in position, army against army. 22 And David gave his parcels into the hands of the keeper of the army stores, and went running to the army and came to his brothers to get knowledge about them. 23 And while he was talking to them, the fighter, the Philistine of Gath, Goliath by name, came out from the Philistines' lines and said the same words, in David's hearing. 24 And all the men of Israel, when they saw him, went in flight, overcome with fear. 25 And the men of Israel said, Have you seen this man? Clearly he has come out to put shame on Israel: and it is certain that if any man overcomes him, the king will give that man great wealth, and will give him his daughter, and make his father's family free in Israel. 26 And David said to the men near him, What will be done to the man who overcomes this Philistine and takes away the shame from Israel? for who is this Philistine, a man without circumcision, that he has put shame on the armies of the living God? 27 And the people gave him this answer, So it will be done to the man who overcomes him. 28 And Eliab, his oldest brother, hearing what David said to the men, was moved to wrath against David, and said, Why have you come here? Into whose care have you given that little flock of sheep in the waste land? I have knowledge of your pride and the evil of your heart, you have come down to see the fight. 29 And David said, What have I done now? was it not only a word? 30 And turning away from him to one of the other men, he said the same words: and the people gave him the same answer.

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.
