2 Samuel 21:16-17

JPS_ASV_Byz(i) 16 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 new armour, thought to have slain David. 17 But Abishai the son of Zeruiah succoured him, and smote the Philistine, and killed him. Then the men of David swore unto him, saying: 'Thou shalt go no more out with us to battle, that thou quench not the lamp of Israel.'
