Ether 8
Somehow I always gloss over the fact that the Jaredites brought records with them across the ocean.
Those who varied from the wished of Akish would be beheaded and those who divulged the secret would be killed (though not necessarily beheaded). This sounds not unlike the honor killings found among some believers of Islam. Actually, it sounds like the Dannites, the Inquisition, and every other perversion known among religions.
