Ether 11:12

And it came to pass in the days of Ethem, there came many prophets and prophesied again unto the people; yea, they did prophesy that the Lord would utterly destroy them from off the face of the earth, except they repented of their iniquities.

When Ethem was king, many prophets came again. They told the people that the Lord would completely destroy them unless they stopped sinning.

During Ethem’s time, prophets appeared again and warned the people: the Lord would completely wipe them off the face of the earth unless they stopped their evil.
