PEARL OF GREAT PRICE
Kolob is the name of a great governing star. See Pearl of Great Price, page 39. Kolob is not a Nephite name, but is given a place here for convenience.
HEBREW
Kokab in Hebrew means "star." The difference which occurs in the orthography of these two words—Kolob and Kokab—might easily be effected during the years which elapsed after Abraham wrote his book down to the time when Moses penned Genesis 1:16, where the Biblical word Kokab is first used. Colob is also found among the names by which the great Maya nation was anciently known. Kolob as Abraham made use of the word designates a great governing world, and since the Mayas once governed an empire, they themselves probably assumed the name Colob in compliment to their one-time position as rulers and governors of tribes and nations.
