Matthew 24:26
If they shall say to you, behold he is in the desert (Islam); go not forth: behold, he is in the secret chambers (Mormon); believe it not.
Mormon = Desert = Utah Secret Chamber = Cumorah Hall (chamber) in New York, claims of found stone chest with bronze tablets, on which holy records were written; believe it not
Islam = Desert = Arabia Secret Chamber = Cave , claims he is messenger; believe it or not
