Ether 10:33

And in the days of Com there began to be robbers in the land; and they adopted the old plans, and administered oaths after the manner of the ancients, and sought again to destroy the kingdom.

When Com was king, robbers started coming to the land. They used the old plans. They made oaths like the people long ago. They tried to destroy the kingdom again.

During Com’s reign, robbers appeared in the land. They revived the ancient secret plans, swore the old oaths, and once again tried to destroy the kingdom.
