Ether 4

And now I, Moroni, proceed with my record. Therefore behold, it came to pass that because of the secret combinations of Akish and his friends, behold, they did overthrow the kingdom of Omer. Nevertheless, the Lord was merciful unto Omer, and also to his sons and to his daughters who did not seek his destruction. And the Lord warned Omer in a dream that he should depart out of the land.
