"Ham" translated "heat," "passion," "hotness" denotes a symbol of the creaturely sensuality, the emotions of man.  

Ham is the youngest son of the righteous Noah, who by the fulfillment of God's Commandments, following the learned Revelations, so "prepared", created the "Ark", i.e. the saving, pious way of life for his spiritual "House", i.e. for the followers of his faith.

"Ham" is a symbol of one of the three nations, spiritually born by the righteous Noah, who are dismissive, skeptical, cynical about the origins of their original true faith, materialistic people who have become followers of false beliefs, false doctrines.
