3. To honor the prelates
4. To honor the lords and warriors
5. About true judgement and patience
6. About admitting guests, newcomers; and patronizing them (this is about a kind of a settlers, traveling priests, knights, artists, artisans; exiles and those who look for new home and such)
7. About the weight of the Council
8. Sons should follow the ancestors
9. Keep praying
10. About piety, clemency and the other virtues
