How is greed and gluttony related? 1Tim 3:8, Proverbs 15:27, Matthew 23:25 (excess KJV/Greed ESV) meaning robbery, Lev. 25:35-38. Also, the book Graham Tomlin, “The Seven Deadly Sins: Life’s Most Toxic Habits,” is a good reference for understanding. He discusses self-interest, rest, giving etc and how it relates to greed.
