God has Ether give the people one last chance. He goes to Coriantumr and lays out the future, including that the people would be destroyed, and that Coriantumr would survive and live to see another people who would receive the promise of the land.
Coriantumr does not repent. Coriantumr turns against Ether and attempts to kill him. Although not stated, it is certain that the Lord’s protection assisted Ether to escape and return to his cave.
