2 Samuel 21
16 Ref and Ishbibenob, who was of the sons of the giant, the weight of whose spear was three hundred [shekels] of brass in weight, he being girded with a new [sword], thought to have slain David.
17 Ref But Abishai the son of Zeruiah helped him, and struck the Philistine, and killed him. Then the men of David swore to him, saying, You shall go no more out with us to battle, that you don't quench the lamp of Israel.
