According to the Book of Mormon, King Noah was a wicked monarch best known for burning the prophet Abinadi at the stake. King Noah, described in the Book of Mosiah, is said to have presided over a wicked kingdom guided by false priests. Noah succeeds his father Zeniff, and is succeeded by his son Limhi.
Noah's father, Zeniff, led a group of Nephites into the land of their 'first inheritance' (the land originally settled by Lehi and his descendants upon their arrival in the Americas). Zeniff had made an agreement with the Lamanites in the area, but wars between the two peoples inevitably ensued. Upon his death Zeniff conferred the kingdom on Noah, who seems to have been far less diligent in preparing and protecting his people against their enemies than his father. Noah was an extremely wicked man and he taxed his people heavily, spending the money on extravagances and wickedness. Possibly the greatest wrong he did his subjects, however, was to teach them to follow his own wicked ways. He deposed the righteous priests who had been appointed by his father and replaced them with prideful ones. Through vanity and flattery they led the people to commit the same sins that they themselves did. Some of the sins that are listed are pride, laziness, idolatry, whoredoms, adultery, drunkenness, and riotous living.
The prophet Abinadi was sent to preach repentance to Noah's people, but was not immediately successful. He was imprisoned and taken before King Noah and his priests. They attempted to "cross him" (or prove him a liar) by asking difficult questions concerning the interpretation of scriptures, including an excerpt from Isaiah, but were unable to do so. Abinadi began to teach them the Ten Commandments and they attempted to "do away with him" but were unable to touch him because he was protected by the power of God. He continued to teach them the rest of the Ten Commandments, as well as to interpret further writings of Isaiah and teach them about Jesus Christ. He finished by testifying that redemption comes through Christ. Abinadi, having delivered his message, was executed by fire. As he was dying he prophesied that Noah and his priests would suffer death in a similar manner.
One of the priests of Noah, a young man named Alma, believed Abinadi's words and pleaded with the king to spare the prophet's life. Alma was cast out, and was forced to hide so that the servants of the king would not kill him. He taught the words of Abinadi to more of the people, and many believed him. He also became a great prophet and religious leader among the rest of the Nephites later in his life. Hence, Abinadi was successful in his mission although he died a martyr and only one man believed his teachings. King Noah's wickedness and oppression of his people continued. Alma and his followers left Noah's people and the king's army were unable to follow them. A minority of Noah's people became angry with him, including a man named Gideon who swore to kill the king. They fought, and Noah saw that he was about to lose so he fled to a tower. From the top of the tower he saw an army of Lamanites about to attack and convinced Gideon to spare him so that he could lead the people to safety.
