3 Nephi 3:15

yea, he said unto them, As the Lord liveth, except ye repent of all your iniquities, and cry unto the Lord, that they would in no wise be delivered out of the hands of those Gadianton robbers.

He said to them: As the Lord lives, if you do not turn away from all your sins and pray to the Lord, you will not be saved from these Gadianton robbers.

He told them, “As surely as the Lord lives, unless you turn away from your sins and cry out to him, you won’t be delivered from these robbers.”
