2 Samuel 21:15-17

MSB(i) 15 Once again the Philistines waged war against Israel, and David and his servants went down and fought against the Philistines; but David became exhausted. 16 Then Ishbi-benob, a descendant of Rapha, whose bronze spear weighed three hundred shekels and who was bearing a new sword, resolved to kill David. 17 But Abishai son of Zeruiah came to his aid, struck the Philistine, and killed him. Then David’s men swore to him, “You must never again go out with us to battle, so that the lamp of Israel may not be extinguished.”
