The text if very deliberate to tell us that Zaccheus was a wealthy man. Jesus tells him, "It is necessary for me to go to your house today." That is an interesting way to talk to a rich man, particularly a rich mobster-type man. The conclusion of the conversation is an editorial comment, "The Son of Man came to seek and to save the lost." I did not remember that comment to be the follow-up to talking with a rich man.
Jesus told the parable of the servants and their minas so that we would know the kingdom is about to be revealed. The stewardship of these servants is in the context of enemies of the king! Faithfulness is more important when the context is hostile to the king. The unfaithful servant showed that he was one who did not want the rule of the king. He was on the other side.
