2 Samuel 21:15-17

Darby(i) 15 And the Philistines had yet war again with Israel; and David went down, and his servants with him, and fought with the Philistines. And David was exhausted. 16 And Ishbibenob, who was of the children of Raphah -- the weight of his lance was three hundred shekels of bronze, and he was girded with new [armour] -- thought to smite David. 17 And Abishai the son of Zeruiah succoured him, and smote the Philistine and killed him. Then the men of David swore to him, saying, Thou shalt go no more out with us to battle, that thou quench not the lamp of Israel.
