2 Samuel 21:15-16
Israel Engages in Various Battles with the Philistines
21:15 Another battle was fought between the Philistines and Israel. So David went down with his soldiers and fought the Philistines. David became exhausted.
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.
