What does the Bible say about being a great man?

In 2 Samuel 19, Barzillai is described as a very great man because of his loyalty to King David, which involved significant personal sacrifice. A great man, from a biblical perspective, is one who prioritizes God's kingdom and His righteousness over personal gain or comfort. This is evident in Barzillai's actions as he provided sustenance to David while he was in exile, demonstrating both his allegiance to God’s appointed king and his willingness to risk his own safety for what is right. God's measure of greatness contrasts sharply with worldly views, emphasizing selflessness, humility, and loyalty to God's authority.
