Book of Mormon: Zemnarihah–The Evil Fruit of the Corrupt Tree? by grego
@2017

So I was reading this:
3 Nephi 4:28 And their leader, Zemnarihah, was taken and hanged upon a tree, yea, even upon the top thereof until he was dead. And when they had hanged him until he was dead they did fell the tree to the earth, and did cry with a loud voice, saying…

and I wondered about why. Then this came into mind:

3 Nephi 14:16-19:
16 Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?
17 Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.
18 A good tree cannot bring forth evil fruit, neither a corrupt tree bring forth good fruit.
19 Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.

Was Zemnarihah, hanged on the tree, a literal fruit? Not down on a branch, just above the ground (no low-hanging fruit!), but “upon the top thereof”. Was that tree which bore evil fruit, a corrupt tree, that was then hewn down?
