In the 13th chapter of Ether, Moroni tells us that Ether went to Coriantumr and prophesied that if he did not repent, all his people would be destroyed except Coriantumr. Ether 13:20-22:
20 And in the second year the word of the Lord came to Ether, that he should go and prophesy unto Coriantumr that, if he would repent, and all his household, the Lord would give unto him his kingdom and spare the people—
21 Otherwise they should be destroyed, and all his household save it were himself. And he should only live to see the fulfilling of the prophecies which had been spoken concerning another people receiving the land for their inheritance; and Coriantumr should receive a burial by them; and every soul should be destroyed save it were Coriantumr.
22 And it came to pass that Coriantumr repented not, neither his household, neither the people; and the wars ceased not; and they sought to kill Ether, but he fled from before them and hid again in the cavity of the rock.
That this prophecy was well known is attested by Ether 14:24:
24 Nevertheless, Shiz did anot cease to pursue Coriantumr; for he had sworn to avenge himself upon Coriantumr of the blood of his brother, who had been slain, and the word of the Lord which came to Ether that Coriantumr should not fall by the sword.
Shiz is overly eager to kill Coriantumr to falsify the prophecy. [Read more…] about Ether’s Prophecy
