The first paragraph is the closest thing to a preamble, explaining why the laws were being written. It shows how council members disagreed (remembered different minds) on what the traditional law was. Don't interpret this as slave rights; the Pe Yansi case was probably the last straw of many cases of differing judicial memory
Pe Yansi sued his slave at law.
The council remembered different minds.
They wrote the law on stone [so it] wouldn't be argued over.
There will be three classes: council, people, king.
The council will make the laws to protect the people.
The king will make the army to protect the people.
The council will replace [impeach] the king at his successor's birthday.
The king chooses the council members.
