Helaman 6:26–27

Now behold, those secret oaths and covenants did not come forth unto Gadianton from the records which were delivered unto Helaman; but behold, they were put into the heart of Gadianton by that same being who did entice our first parents to partake of the forbidden fruit—Yea, that same being who did plot with Cain, that if he would murder his brother Abel it should not be known unto the world. And he did plot with Cain and his followers from that time forth.
