2 Samuel 21:16-17

21:16 Now Ishbi-Benob, one of the descendants of Rapha, had a spear that weighed three hundred bronze shekels, and he was armed with a new weapon. He had said that he would kill David. 21:17 But Abishai the son of Zeruiah came to David’s aid, striking the Philistine down and killing him. Then David’s men took an oath saying, “You will not go out to battle with us again! You must not extinguish the lamp of Israel!”
