1 Nephi 22:13

And the blood of that great and abominable church, which is the whore of all the earth, shall turn upon their own heads: for they shall war among themselves, and the sword of their own hands shall fall upon their own heads, and they shall be drunken with their own blood.

That great and evil church will destroy itself. It is like an unfaithful woman to all the earth. They will fight among themselves. They will hurt themselves with their own weapons. They will be covered with their own blood.

“As for that corrupt and evil church—that corrupt system that has poisoned the whole earth—it will destroy itself. Its followers will turn on each other, killing themselves with their own swords. They’ll become drunk on their own blood.”
