Benaiah (Warrior living at the time of United Monarchy)

Benaiah commanded David's personal bodyguard and was famous even before that role for killing a lion in a pit on a snowy day and defeating an Egyptian giant by wrestling away the giant's own spear and killing him with it. He stayed loyal to Solomon during Adonijah's attempted coup and personally executed both Joab and Adonijah on Solomon's orders afterward, and Solomon rewarded him by making him commander of the entire army in Joab's place.
