Corihor was a Jaredite, son of King Kib and a descendant of Jared through Orihah (Ether 7:3). At thirty-two he rebelled against his father, leaving to dwell in the land of Nehor, where he had sons and daughters who became “exceedingly fair,” and he drew away many people after him (Ether 7:4).
After raising an army, Corihor marched against the land of Moron, where the king dwelt, and took his father captive, which brought to pass the brother of Jared’s saying that the people would be brought into captivity (Ether 7:5). Kib remained in captivity under Corihor until he was very old (Ether 7:7).
Corihor’s brother Shule, born to Kib while still in captivity, made swords of steel from the hill Ephraim, armed his followers, and gave battle to Corihor at the city of Nehor, taking the kingdom and restoring it to their father Kib (Ether 7:8-9). Corihor later repented of the evils he had done, and Shule, now king, gave him power in the kingdom (Ether 7:13).
Corihor had many sons and daughters, among them Noah, who rebelled against Shule and against Corihor and drew away his brother Cohor (Ether 7:14-15). Both Noah and Cohor are named again, with Corihor, among the fair sons and daughters who did not repent (Ether 13:17).
