2 Samuel 21:16-18

16A descendant of Rapha who was called Ishbi-Benob said that he would kill David. He had a bronze spear that weighed 3½ kilograms and he had a new sword.

17But Zeruiah's son Abishai saved David. Abishai knocked down the Philistine and he killed him. So David's men said very strongly, ‘Our king, you must never again come out with us to fight a battle. You are like Israel's light. We do not want your life to finish.’

18Some time after that, the Israelites fought a battle against the Philistines at Gob. In that battle, Sibbecai from Hushah killed Saph, a descendant of Rapha.
