1st Samuel 17:32 And David said to Saul, Let no man's heart fail because of him; thy servant will go and fight with this Philistine. 33 And Saul said to David, Thou art not able to go against this Philistine to fight with him: for thou art but a youth, and he a man of war from his youth.
[Patriarchs & Prophets pp 646>647] 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.” 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. Goliath was filled with amazement and anger. “Am I a dog,” he exclaimed, “that thou comest to me with staves?” Then he poured upon David the most terrible curses by all the gods of his knowledge. He cried in derision, “Come to me, and I will give thy flesh unto the fowls of the air, and to the beasts of the field.”
1st Samuel 17:42 And when the Philistine looked about, and saw David, he disdained him: for he was but a youth, and ruddy, and of a fair countenance. 43 And the Philistine said unto David, Am I a dog, that thou comest to me with staves? And the Philistine cursed David by his gods.
May God add His blessing to the study of His word. "Good night" and God bless!
