All always carry swords at their sides, because they do not trust one another and because a ruse is a commonplace thing among them. If one succeeds in acquiring an estate, immediately his brother or friend becomes envious and attempts either to kill him or rob him.
If a son is born unto a family, the father takes a naked sword, places before the newly-born infant, and says: “I leave you no inheritance except this sword, and you will have but that which you will be able to conquer with it.”
