I'm trying to understand what appears (for me) to be a conflict regarding the Biblical eastern boundary of the "Promised land".
It seems that the land promised to the fathers went all the way as east as the Euphrates. There are two verses, in particular I'm viewing:
Breishit 15:18 G-d promises to Avraham and his descendants the land from the Egyptian river to the Euphrates river.
Devarim 1:7-8 In verse 7, Moshe tells B'nai Israel to go to the land until the Euphrates River. In verse 8, Moshe uses the phrase "...that G-d has promised your fathers."
What seems contradictory is that when delineating the land borders for 9 1/2 tribes (Levi doesn't get a portion; and 2 1/2 tribes took their portion East of the Jordan) the Torah marks the eastern border along the Kinneret and the Jordan River - not as far as the Euphrates (Bemidbar 34:10-12.)
The conflict appears to be why G-d limited the eastern border for those remaining tribes to the west of the Jordan. In actuality, it seems that the "promised land"'s eastern border extended to the Euphrates. Why, then, does the Torah in Bemidbar not extend the eastern border for all the tribes to go east of the Jordan?
