God destroys those who worship other gods. 1:12
"From Ham, sprang that race which preserved the curse in the land"
All Egyptians were (are?) cursed by God because Ham saw Noah when he was drunk and naked.
(Genesis 9:20-25) 1:21-24
"Pharaoh being of that lineage by which he could not have the right of Priesthood"
The Pharaoh was black (according to this verse, anyway), and because of that he was banned from the priesthood. (Poor Pharaoh couldn't be a Mormon

the 1978 revelation.)
