2 Samuel 21:15-17

MKJV(i) 15 And again the Philistines warred with Israel. And David went down, and his servants with him, and fought against the Philistines. And David became faint. 16 And Ishbi-benob, who was of the sons of the giant, the weight of whose spear was three hundred shekels of bronze in weight. And he being girded with a new sword thought to kill David. 17 But Abishai the son of Zeruiah came to his aid, and struck the Philistine, and killed him. Then the men of David swore to him, saying, You shall not go out to battle with us any more, so that you do not put out the light of Israel.
