Alma condemns Nehor to death for murdering Gideon.
Alma 1:13-14, Book of Mormon, The Church of Jesus Christ of Latter-Day Saints, accessed May 31, 2022
And thou hast shed the blood of a righteous man, yea, a man who has done much good among this people; and were we to spare thee his blood would come upon us for vengeance.
Therefore thou art condemned to die, according to the law which has been given us by Mosiah, our last king; and it has been acknowledged by this people; therefore this people must abide by the law.
