Ether 13:17

but he repented not, neither his fair sons nor daughters; neither the fair sons and daughters of Cohor; neither the fair sons and daughters of Corihor; and in fine, there was none of the fair sons and daughters upon the face of the whole earth, which repented of their sins;

But he did not turn away from his sins. His fair sons and daughters did not turn away from their sins. The fair sons and daughters of Cohor did not turn away from their sins. The fair sons and daughters of Corihor did not turn away from their sins. In fact, none of the fair sons and daughters on the whole earth turned away from their sins.

But he didn’t repent. Neither did his sons and daughters, nor the sons and daughters of Cohor, nor the sons and daughters of Corihor. In fact, not a single person in that whole generation repented of their sins.
