The prophet Nephi is so heartbroken about the wickedness of the Nephites (the Gadianton Robbers had overtaken the government) that he goes out and prays on his garden tower. Some people in the city stopped to listen. When Nephi noticed a crowd gathered he started to teach the people and prophesy. Telling them if they did not repent they would all be destroyed. Nephi told them their Chief Judge was murdered by his brother. 5 men ran off to see if that was true. It was! The Gadianton Robbers tried to get the people to believe Nephi had arranged with someone to kill the Chief Judge. Nephi said to go and ask his brother if he had killed his brother. He said He will act shocked but when you ask about the blood on his cloak he will confess. Everything happened just as Nephi said it would. Some people believed he had to be a prophet, but most did not want to believe so explained it away. We are so blessed to have prophets that teach us and warn us.
