Shout out to:

David!!! (the king)

And it came to pass, when the Philistine arose, and came and drew nigh to meet David, that David hasted, and ran toward the army to meet the Philistine. And David put his hand in his bag, and took thence a stone, and slang it, and smote the Philistine in his forehead, that the stone sunk into his forehead; and he fell upon his face to the earth. So David prevailed over the Philistine with a sling and with a stone, and smote the Philistine, and slew him; but there was no sword in the hand of David. Therefore David ran, and stood upon the Philistine, and took his sword, and drew it out of the sheath thereof, and slew him, and cut off his head therewith. And when the Philistines saw their champion was dead, they fled. (1 Samuel 17:48-51 KJV)

Not only was he a great warrior but he was merciful and would not kill the man who God anointed, though Saul wanted to kill him.

And David sent messengers unto the men of Jabesh–gilead, and said unto them, Blessed be ye of the Lord, that ye have shewed this kindness unto your lord, even unto Saul, and have buried him. And now the Lord shew kindness and truth unto you: and I also will requite you this kindness, because ye have done this thing. (2 Samuel 2:5, 6 KJV)

And David said, Is there yet any that is left of the house of Saul, that I may shew him kindness for Jonathan's sake? (2 Samuel 9:1 KJV)


Obviously I am reading out of Samuel right now...
