Abraham 1

 In the book of Abraham, we learn that - 

"Now the first government of Egypt was established by Pharaoh, the eldest son of Egyptus, the daughter of Ham, and it was after the manner of the government of Ham, which was patriarchal.

26 Pharaoh, being a righteous man, established his kingdom and judged his people wisely and justly all his days, seeking earnestly to imitate that order established by the fathers in the first generations, in the days of the first patriarchal reign, even in the reign of Adam, and also of Noah, his father, who blessed him with the blessings of the earth, and with the blessings of wisdom, but cursed him as pertaining to the Priesthood.

27 Now, Pharaoh being of that lineage by which he could not have the right of Priesthood, notwithstanding the Pharaohs would fain claim it from Noah, through Ham..."  Abraham 1:25-27

We also learn that Abraham held - 

"...the records of the fathers, even the patriarchs, concerning the right of Priesthood, the Lord my God preserved in mine own hands; therefore a knowledge of the beginning of the creation, and also of the planets, and of the stars, as they were made known unto the fathers, have I kept even unto this day, and I shall endeavor to write some of these things upon this record, for the benefit of my posterity that shall come after me."  Abraham 1:31
