The leopard does not change his spots - Proverb for January 17

The source of this proverb is from the Bible, Jeremiah 13:23 where it says "Can an Ethiopian change his skin or a leopard its spots? Neither can you do good who are accustomed to doing evil." (NIV)

Since the leopard is a hunter and a dangerous animal, it represents a bad person. The "spots" represents the particular undesirable or bad characteristic of the person in question. It also implies that this characteristic cannot be changed or hidden.

So the meaning of this proverb is that a person cannot change their character traits, especially the negative ones.
