1 Samuel 17:13-23

13 and the three eldest sons of Jesse go, they have gone after Saul to battle; and the name of his three sons who have gone into battle [are] Eliab the first-born, and his second Abinadab, and the third Shammah.
14 And David is the youngest, and the three eldest have gone after Saul,
15 and David is going and returning from Saul, to feed the flock of his father at Beth-Lehem.
16 And the Philistine draweth nigh, morning and evening, and stationeth himself forty days.
17 And Jesse saith to David his son, `Take, I pray thee, to thy brethren, an ephah of this roasted [corn], and these ten loaves, and run to the camp to thy brethren;
18 and these ten cuttings of the cheese thou dost take in to the head of the thousand, and thy brethren thou dost inspect for welfare, and their pledge dost receive.'
19 And Saul, and they, and all the men of Israel [are] in the valley of Elah, fighting with the Philistines.
20 And David riseth early in the morning, and leaveth the flock to a keeper, and lifteth up, and goeth, as Jesse commanded him, and he cometh in to the path, and to the force which is going out unto the rank, and they have shouted for battle;
21 and Israel and the Philistines set in array rank to meet rank.
22 And David letteth down the goods from off him on the hand of a keeper of the goods, and runneth into the rank, and cometh and asketh of his brethren of welfare.
23 And he is speaking with them, and lo, a man of the duellists is coming up, Goliath the Philistine [is] his name, of Gath, out of the ranks of the Philistines, and he speaketh according to those words, and David heareth;

1 Samuel 17:13-23 Meaning and Commentary

INTRODUCTION TO FIRST SAMUEL 17

This chapter relates how the armies of Israel, and of the Philistines, prepared for battle, and where, 1Sa 17:1-3, describes a champion of the Philistines, who defied the armies of Israel, 1Sa 17:4-11, and while he was so doing, it informs us that David came into the camp, and he heard his words, and signified to one and another his inclination to fight with him, 1Sa 17:12-30, which being reported to Saul, David was sent for by him, and much discourse passed between them about it, 1Sa 17:31-37 when we are told the manner in which he engaged with the Philistine, and the victory he obtained over him, 1Sa 17:38-51 upon which the Philistines fled, and Israel pursued them; and on account of this action David was taken notice of by Saul, and brought to court again, as the following chapter shows, 1Sa 17:52-58.
