Joseph Smith is a false prohphet.
13:15, 15:18, 17:8, 28:13-14
# "In the fourth generation they [Abraham's descendants] shall come hither again." But, if we count Abraham, then their return occurred after seven generations: Abraham, Isaac (Gen.21:1-3), Jacob (Gen.25:19-26), Levi (Gen.35:22-23), Kohath (Ex.6:16), Amramn (Ex.6:18), and Moses (Ex.6:20). Joseph Smith claimed that Jesus was to return 56 year's from the day of his prophecy. 12:6
# God promises to cast out seven nations including the Amorites, Canaanites, and the Jebusites.
