Ether 8:20

And now I, Moroni, do not write the manner of their oaths and combinations, for it hath been made known unto me that they are had among all people, and they are had among the Lamanites,

I, Moroni, will not write down how their oaths and secret groups work. I know these groups exist among all people. They exist among the Lamanites.

I, Moroni, won’t write down the details of their oaths and conspiracies. I know they exist among all peoples—even among the Lamanites.
