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. 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.David was the youngest; the three eldest followed Saul, but David went back and forth from Saul to feed his father’s sheep at Bethlehem. For forty days the Philistine came forward and took his stand, morning and evening. 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; also take these ten cheeses to the commander of their thousand. See how your brothers fare, and bring some token from them.” Now Saul, and they, and all the men of Israel, were in the valley of Elah, fighting with the Philistines. 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. Israel and the Philistines drew up for battle, army against army. David left the things in charge of the keeper of the baggage, ran to the ranks, and went and greeted his brothers. 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. (1 Samuel 17:12-23, NRSV)
David went back and forth between the army of Saul where his oldest brothers were and the sheep he was tending for his father. And One day his father told him to take food to his brothers and the commander of the forces.
He did and when he found his brothers he heard the taunting of the man Goliath.
David didn’t like this taunting, but the army was scared of the image of the man Goliath because our problems always seem bigger than they really are.
