hmm, Solomon had control over demons but that be from outside the bible, David has good feats but off the top of my head it would probably be Samson who could kill 1000 men with a donkeys jawbone and bring down a temple with his bare hands. Noah is also a contender if you accept there is some kind of numenorean blood thing going on where the closer to adam and eve you are the more powerful and beyond human you are, he did live for over 300 years and had to gather some dangerous animals.

alexander the great is mentioned in maccabes so he's the best general.
