KJV Gen 48:5-6 reads:
And
now thy two sons, Ephraim and Manasseh, which were born unto thee in the land
of Egypt before I came unto thee into Egypt, are mine; as Reuben and Simeon,
they shall be mine. And thy issue, which thou begettest after them, shall be
thine, and shall be called after the name of their brethren in their
inheritance.
Joseph Smith expanded upon this text
and the promises made to Ephraim and Manasseh. Old Testament Manuscript 2,
pages 62-63 reads:
and now, of thy two sons, Epraim and Manassah, which were born [u]<u>nto
thee in the Land of Egypt, before I came unto thee in<to> Egypt; behold,
thay are mine, and the God of my Fathe[r]<rs> shall bless them; even as Reuben and Simeon
they shall also be blessed, for they are mine; Wherefore they shall be called
after my name, <(>therefore they were called Israel.<)> and thy
Issue, which thou begetest after them, shall be thin<e>, and shall be called
after the name of there brethren in there inheritence, in there tribes; therefore they were called the
tribes of Manasseh & <of> Ephraim. and Jacob said unto Josep[t]<h>,
when the God of my Fathers appeared unto me in Luz, in the Land of Canaan; he
sware unto me, that he would give unto me, and unto my seed, the land for an
everlasting possession, therefore, O my son, he hath blessed me in raising thee
up to be a servant unto me, in saving my house from death, in delivering my people, thy Brethren, from famin which
was sore in the Land; wherefore the god of thy fathers shall bless thee, and
the fruit of thy loins, that they shall be blessed above thy brethren, and
above thy fathers house; for thou hast prevailed, and thy Fathers house has
bowed down unto thee, even as it was shewen unto thee, before thou wast sold
into Egypt, by the hands of thy Brethren; wherefore thy Brethren shall bow down
unto thee from Je Generation to generation, unto the fruit of thy loins
for ever[,]<;> to be a <for thou shalt> be a light
unto my people, to deliver them in the days of there captivity, from there
bondage; and to p bring salvation unto them, \when thay are alltogether
bowed down uder sin.
