God was teaching David lessons of trust. As Moses was trained for his work, so the Lord was fitting the son of Jesse to become the guide of His chosen people. In his watchcare for his flocks, he was gaining an appreciation of the care that the Great Shepherd has for the sheep of His pasture. (PP 644.1) MC VC

The lonely hills and the wild ravines where David wandered with his flocks were the lurking place of beasts of prey. Not infrequently the lion from the thickets by the Jordan, or the bear from his lair among the hills, came, fierce with hunger, to attack the flocks. According to the custom of his time, David was armed only with his sling and shepherd’s staff; yet he early gave proof of his strength and courage in protecting his charge. Afterward describing these encounters, he said: “When there came a lion, or a bear, and took a lamb out of the flock, I went out after him, and smote him, and delivered it out of his mouth: and when he arose against me, I caught him by his beard, and smote him, and slew him.” 1 Samuel 17:34, 35, R.V. His experience in these matters proved the heart of David and developed in him courage and fortitude and faith. (PP 644.2) MC VC

Even before he was summoned to the court of Saul, David had distinguished himself by deeds of valor. The officer who brought him to the notice of the king declared him to be “a mighty valiant man, and a man of war, and prudent in matters,” and he said, “The Lord is with him.” 1 Samuel 16:18. (PP 644.3) MC VC

When war was declared by Israel against the Philistines, three of the sons of Jesse joined the army under Saul; but David remained at home. After a time, however, he went to visit the camp of Saul. By his father’s direction he was to carry a message and a gift to his elder brothers and to learn if they were still in safety and health. But, unknown to Jesse, the youthful shepherd had been entrusted with a higher mission. The armies of Israel were in peril, and David had been directed by an angel to save his people. (PP 644.4) MC VC

The words of David were repeated to the king, who summoned the youth before him. Saul listened with astonishment to the words of the shepherd, as he said, “Let no man’s heart fail because of him; thy servant will go and fight with this Philistine.” 1 Samuel 17:32. Saul strove to turn David from his purpose, but the young man was not to be moved. He replied in a simple, unassuming way, relating his experiences while guarding his father’s flocks. And he said, “The Lord that delivered me out of the paw of the lion, and out of the paw of the bear, He will deliver me out of the hand of this Philistine. And Saul said unto David, Go, and the Lord be with thee.” 1 Samuel 17:37. (PP 646.1) MC VC

For forty days the host of Israel had trembled before the haughty challenge of the Philistine giant. Their hearts failed within them as they looked upon his massive form, in height measuring six cubits and a span. Upon his head was a helmet of brass, he was clothed with a coat of mail that weighed five thousand shekels, and he had greaves of brass upon his legs. The coat was made of plates of brass that overlaid one another, like the scales of a fish, and they were so closely joined that no dart or arrow could possibly penetrate the armor. At his back the giant bore a huge javelin, or lance, also of brass. “The staff of his spear was like a weaver’s beam; and his spear’s head weighed six hundred shekels of iron; and one bearing a shield went before him.” 1 Samuel 17:7. (PP 646.2) MC VC

Morning and evening Goliath had approached the camp of Israel, saying with a loud voice, “Why are ye come out to set your battle in array? am not I a Philistine, and ye servants to Saul? choose you a man for you, and let him come down to me. If he be able to fight with me, and to kill me, then will we be your servants: but if I prevail against him, and kill him, then shall ye be our servants, and serve us. And the Philistine said, I defy the armies of Israel this day; give me a man, that we may fight together.” 1 Samuel 17:8~10. (PP 646.3) MC VC

Though Saul had given David permission to accept Goliath’s challenge, the king had small hope that David would be successful in his courageous undertaking. Command was given to clothe the youth in the king’s own armor. The heavy helmet of brass was put upon his head, and the coat of mail was placed upon his body; the monarch’s sword was at his side. Thus equipped, he started upon his errand, but erelong began to retrace his steps. The first thought in the minds of the anxious spectators was that David had decided not to risk his life in meeting an antagonist in so unequal an encounter. But this was far from the thought of the brave young man. When he returned to Saul he begged permission to lay aside the heavy armor, saying, “I cannot go with these; for I have not proved them.” 1 Samuel 17:39. He laid off the king’s armor, and in its stead took only his staff in his hand, with his shepherd’s scrip and a simple sling. Choosing five smooth stones out of the brook, he put them in his bag, and, with his sling in his hand, drew near to the Philistine. The giant strode boldly forward, expecting to meet the mightiest of the warriors of Israel. His armor-bearer walked before him, and he looked as if nothing could withstand him. As he came nearer to David he saw but a stripling, called a boy because of his youth. David’s countenance was ruddy with health, and his well-knit form, unprotected by armor, was displayed to advantage; yet between its youthful outline and the massive proportions of the Philistine, there was a marked contrast.
