Ishbi-Benob was a Philistine warrior descended from giants. The story of Ishbi-Benob is well-known in the Bible because he nearly defeated King David during a battle. Ishbi-Benob was imposing and skilled in combat. The head of his spear alone weighed more than three kilograms. He was a descendant of the Rephaim and likely lived in Nob.
The biblical text informs us that in a certain battle, King David was already very tired and could not defeat Ishbi-Benob on his own. Then, when the Philistine giant was about to end his life, Abishai, David's nephew, defeated the giant Ishbi-Benob and saved David's life. After this confrontation with Ishbi-Benob, King David, who was seen as the “Lamp of Israel,” was advised by his men not to fight in battles anymore.
