Samuel the Lamanite was called to preach repentance to the Nephites who were not obeying God or following his teachings. Some Nephites repented, most got angry and tried to hurt Samuel by shooting arrows at him or throwing rocks at him. Samuel was not afraid, He was obeying God and that mattered most to him. Samuel prophesied many things to the Nephites including the signs of his birth, which would happen in 5 years. Samuel left and was never heard of around Zarahemla again. Everything Samuel prophesied came true. He was a prophet of God.
