The allocation of the land of Israel to the descendants of Shem is made in documents written by Noah himself (8:10-11).
And it came to pass at the beginning of the thirty-third jubilee, that they divided the land (in) three parts, for Shem, Ham, and Japheth, according to the inheritance of each, in the first year in the first week, while one of us who were sent was dwelling with them. 11 And he called his children, and they came to him, they and their children. And he divided by lot the land which his three sons would possess. And they stretched out their hands and took the document from the bosom of Noah, their father. OTP 2:72.
Noah rejoiced that his son Shem should receive this land, and blessed his son saying “may the Lord dwell in the dwelling place of Shem” (8:18). In this territory are the three most holy places on earth: Eden, Sinai and Zion (8:19-21). Of the territories assigned to the three sons of Noah, only Shem’s is described as “very good,” an echo of the text of the creation story itself (8:21, cf Gen 1:31). When Canaan sees this good land he seizes it from his brother, incurring a curse (10:30).
After the flood, Noah makes a sacrifice to atone for the defilement of the land (6:2). The description of this sacrifice in Jubilees 7:30-33 is greatly expanded from the text in Genesis 9 and is a careful interweaving of texts from the Law on the defilement of the land (Halpurn-Amaru, Rewriting the Bible, 27). In 7:34, Noah’s sons will be like plants in the land (medr) if they are righteous. This may echo the prophets (Jer 11:17, Amos 9:15) as well as 1 Enoch (10:16, 93:5, 10).
When Abraham is taking possession of the land for the first time, the Lord promises to give the land to Abraham’s descendants forever (15:10). In Abraham’s farewell to his children in chapter 20 he implores his children to not worship false gods so that they will remain in the land, blessed with the good things of the land (20:6-10). This section is an echo of the blessings found in Deut 27:15; it is perhaps significant that the writer does not include an equal place to the curses of the covenant.
The emphasis on God’s gift of land to the descendants of Israel is important because many Jewish readers of this book were living outside of Judea. Perhaps the author of Jubilees places the promise of land to the time of Noah in order to assure readers of God’s promise restore the people of Israel to the land in the future, or even to encourage a return to the land at the present time.
How does this idea of land play into the Maccabean revolt? Does the view of Jubilees reflect the same sort of land-theology as 1 Maccabees or 2 Maccabees? It is even possible the idea of the land as a sacred gift of God impacts later Christian writing (and perhaps contemporary theology).
