Ether 11:20

And in the days of Coriantor there also came many prophets, and prophesied of great and marvellous things, and cried repentance unto the people, and except they should repent, the Lord God would execute judgement against them to their utter destruction;

When Coriantor lived, many prophets came too. They talked about great and amazing things. They told the people to change. If the people did not change, the Lord God would completely destroy them.

During Coriantor’s lifetime, more prophets came with incredible warnings. They called the people to turn back, saying that if they didn’t, the Lord God would judge them and destroy them completely.
