The notes below were used as a textual guide for the following broadcast:
##...that his other sons should be named after their brothers [Ephraim and Manasseh] and blessed as well in their blessing..."THY ISSUE, WHICH THOU [have already] BEGETTEST AFTER THEM, SHALL BE THINE". These words would not have been uttered in vain.##Nachmanides is saying that since the blessing expressly mentions Joseph having other sons apart from Ephraim and Manasseh then he must have had them.
##Why did Jacob not command that Manasseh be placed on his left side and Ephraim on his right?This Sage is saying that: Manasseh remained on the right hand side of Jacob. He fulfilled the destiny of Jacob and expressed more the inner being of Jacob. The left hand of Jacob was on the head of Manasseh. The left hand is the weaker hand and the slower one. It indicated that Manasseh would be slower to reach fruition.
Why did Jacob have to cross his hands over?
The truth is that Manasseh is the firstborn!
This is why it says "GUIDING HIS HAND WITTINGLY" (Genesis 48:14). He did not change Manasseh over to the left side) for in truth Manasseh is the firstborn and the most important but he put Ephraim before Manasseh concerning the chronological precedence##.
##The order of placing of the sons was important both in regards to their positioning concerning Joseph and in that concerning Jacob. Concerning Joseph....Ephraim is the one who fulfills his place and most continues his path...Therefore Joseph set Ephraim on his right-hand side to show that Ephraim is the main principle of his might and the continuer of his path...However concerning Jacob it is just the opposite. Manasseh is closer ... to the path of Jacob...Jacob however guided his hands wittingly to indicate that the greatness of Manasseh would not be revealed so soon...Jacob agreed only that Manasseh remain at his right-hand side for he is destined to complete the quality ...of Jacob himself in the building of the Third Temple##.The USA is Manasseh. Britain is Ephraim. The USA became great AFTER Britain.
