And David said to Saul, "Let no man's heart fail because of him; your servant will go and fight with this Philistine."
And Saul said to David, "You are not able to go against this Philistine to fight with him; for you are but a youth, and he has been a man of war from his youth."
But David said to Saul, "Your servant used to keep sheep for his father; and when there came a lion, or a bear, and took a lamb from the flock,
I went after him and smote him and delivered it out of his mouth; and if he arose against me, I caught him by his beard, and smote him and killed him.
Your servant has killed both lions and bears; and this uncircumcised Philistine shall be like one of them, seeing he has defied the armies of the living God."
And David said, "The LORD who delivered me from the paw of the lion and from the paw of the bear, will deliver me from the hand of this Philistine." And Saul said to David, "Go, and the LORD be with you!"
Then Saul clothed David with his armor; he put a helmet of bronze on his head, and clothed him with a coat of mail.
And David girded his sword over his armor, and he tried in vain to go, for he was not used to them. Then David said to Saul, "I cannot go with these; for I am not used to them." And David put them off.
Then he took his staff in his hand, and chose five smooth stones from the brook, and put them in his shepherd's bag or wallet; his sling was in his hand, and he drew near to the Philistine.
And the Philistine came on and drew near to David, with his shield-bearer in front of him.
And when the Philistine looked, and saw David, he disdained him; for he was but a youth, ruddy and comely in appearance.
