Could someone help me understand these lyrics?

Be wise, be brave, says the father to his son be alert, be strong, never bow before anyone.never compromises our ideals before a nations scorn remember my son be on guard it's always calm before the storm.be bold,be daring,never fear going in for the kill be smart,be cunning, live by your elders will .remember your free never to be anyone else's slave for our laws and ideals you'll take with you to the grave........ancient principles of the past are still alive today amidst changes and imposed laws we always found a way I pass to you the power and wisdom my elders pass on to me your heart beats now for your fathers and your family tree.CHORUS:BLOOD,HONOR,LOYALTY 4x.if you live by the sword you die by the sword that's what separates the boys from the men.your bound by honor sworn by loyalty your family your race you'll defend.the world is made up of beggars,thieves,peasants,kings,nobles and lords.judge not a man by the wealth that he wields but by the power of his sword.one can't judge a man's character by how many tales he has sung when the truth lies in his actions and not the work of his tongue.
