They brought David before King Saul. Some years had passed since Saul had met David, and he had grown from a boy to a man, so that Saul did not know him as the shepherd who had played on the harp before him in other days.

Saul said to David:
"You cannot fight with this great giant. You are very young; and he is a man of war, trained from his youth."

And David answered King Saul:
"I am only a shepherd, but I have fought with lions and bears, when they have tried to steal my sheep. And I am not afraid to fight with this Philistine."

Then Saul put his own armor on David—a helmet on his head, and a coat of mail on his body, and a sword at his waist. But Saul was almost a giant, and his armor was far too large for David. David said:
"I am not used to fighting with such weapons as these. Let me fight in my own way."

So David took off Saul's armor. While everybody in the army had been looking on the giant with fear, David had been thinking out the best way for fighting him; and God had given to David a plan. It was to throw the giant off his guard, by appearing weak and helpless; and while so far away that the giant could not reach him with sword or spear, to strike him down with a weapon which the giant would not expect and would not be prepared for.

David took his shepherd's staff in his hand, as though that were to be his weapon. But out of sight, in a bag under his mantle, he had five smooth stones carefully chosen, and a sling,—the weapon that he knew how to use. Then he came out to meet the Philistine.

The giant looked down on the youth and despised him, and laughed.

"Am I a dog?" he said, "that this boy comes to me with a staff? I will give his body to the birds of the air, and the beasts of the field."

And the Philistine cursed David by the gods of his people. And David answered him:

"You come against me with a sword, and a spear, and a dart; but I come to you in the name of the Lord of hosts, the God of the armies of Israel. This day will the Lord give you into my hand. I will strike you down, and take off your head, and the host of the Philistines shall be dead bodies, to be eaten by the birds and the beasts; so that all may know that there is a God in Israel, and that He can save in other ways besides with sword and spear."
