Joseph Smith History 1:33; “He called me by name, and said unto me that he was a messenger sent from the presence of God to me, and that his name was Moroni; that God had a work for me to do; and that my name should be had for good and evil among all nations, kindreds, and tongues, or that it should be both good and evil spoken of among all people.”
Holman Bible Dictionary, Prophets; “The prophets did more than predict the future; their messages called Israel to honor God. Their prophecies were not general principles but specific words corresponding to Israel’s historical context.”
Exodus 3:10; “Come now therefore, and I will send thee unto Pharaoh, that thou mayest bring forth my people the children of Israel out of Egypt.”
I can’t think of one prophet in the Old Testament who laid claim to being known for evil.
