Gen 48:17  And when Joseph saw that his father laid his right hand upon the head of Ephraim, it displeased him: and he held up his father's hand, to remove it from Ephraim's head unto Manasseh's head. 
Gen 48:18  And Joseph said unto his father, Not so, my father: for this is the 
firstborn; put thy right hand upon his head. 
Gen 48:19  And his father refused, and said, I know it, my son, I know it: he also shall become a people, and he also shall be great: but truly his younger brother shall be greater than he, and his seed shall become a multitude of nations. 

The reasons are clear in the bible why Ishmael, the firstborn, was disqualified and replaced by Isaac. Esau, Isaac’s firstborn, was replaced by Jacob, and Reuben, Jacob’s firstborn, was actually replaced by Ephraim after Jacob’s blessings. 

The big mystery is: why was Manasseh replaced? 

Manasseh was divided into two tribes.

Num 34:14  For the tribe of the children of Reuben according to the house of their fathers, and the tribe of the children of Gad according to the house of their fathers, have received their inheritance; and half the tribe of Manasseh have received their inheritance: 

Machir is the son of Manasseh, and has a lot to do with the half tribe.

Gen 50:23  And Joseph saw Ephraim's children of the third generation: the children also of Machir the son of Manasseh were brought up upon Joseph's knees. 

Gilead is the son of Machir, and they grew into a family, known as Gileadites.

Num 26:29  Of the sons of Manasseh: of Machir, the family of the Machirites: and Machir begot Gilead: of Gilead come the family of the Gileadites. 

Machir was a man of war.

Jos 17:1  There was also a lot for the tribe of Manasseh; for he was the firstborn of Joseph; to wit, for Machir the firstborn of Manasseh, the father of Gilead: because he was a man of war, therefore he had Gilead and Bashan. 

Machir was not pure Israelite.

1Ch 7:14  The sons of Manasseh; Ashriel, whom she bore: (but his concubine the Aramitess bore Machir the father of Gilead: 

Gilead is separated from Manasseh, but is still the half tribe of Manasseh, and is still loved by God.

Psa 60:7  Gilead is mine, and Manasseh is mine; Ephraim also is the strength of mine head; Judah is my lawgiver; 

Jair is a Manassite, and is from the half tribe known as the Gileadites.

Num 32:41  And Jair the son of Manasseh went and took the small towns thereof, and called them Havoth-jair. 

Jdg 10:3  And after him arose Jair, a Gileadite, and judged Israel twenty and two years. 

It seems quite probable that America is only the half tribe of Manasseh; and the other half, known as the Gileadites, are still separated to this very day. The Gileadites genealogy is given from Manasseh, to Machir, to Gilead, to Jair. The Gileadites are men of war.

The reason that they lost the birthright may well be, because God knew that they would fight each other.

The ‘Jair men’ of years ago could well be the ‘Germen [Jairmen]’ of today. Is this the reason that God transferred the firstborn status from Manasseh to Ephraim?

Gen 48:14  And Israel stretched out his right hand, and laid it upon Ephraim's head, who was the younger, and his left hand upon Manasseh's head, guiding his hands wittingly; for Manasseh was the firstborn. 

Jer 31:9  They shall come with weeping, and with supplications will I lead them: I will cause them to walk by the rivers of waters in a straight way, wherein they shall not stumble: for I am a father to Israel, and Ephraim is my firstborn. 

Some Germans call themselves Jair men [according to the internet.] Germans have always been part of the colonization of Great Britain, Australia, and America. Germans have fought latter day Joseph in the world wars, trying to get the riches of the covenant, which was taken from them at the blessing. 

Ishmael, and Esau are fighting and plotting to this very day, to get their hands on the birthright promise. It seems very likely that the half tribe of Manasseh [Gileadites] still want the firstborn status, as they have fought Great Britain in two world wars, to try and gain prominence over that country. The half tribe; known as America, have never aspired for greater status than Great Britain. America has fought Britain for independence only: Germany has fought Britain to try and gain prominence over them.

Germans have been instrumental in the colonization of America and Australia. Ach Tung is on signposts in Dan [Ireland]. Normal Germans did not hate Great Britain in the wars. The Nazis were the ones full of hate and cruelty. 

This article is not proof positive, but there has to be some reason why God took the firstborn status from Manasseh. The way the Nazi’s acted, most likely means that they are children of the devil.

It is most probable that Russia is Assur. [Both sound the same, and Russians are white, as the Assyrians are.]
