In Genesis, Rebekah's favorite son is Jacob, and she pushes him to steal the right to rule from his (half-brother?) Esau. She arranges for Jacob to receive from Isaac the blessing due to Isaac's proper heir. This attempt fails, and Jacob is sent away to live with his maternal uncle Laban (avunculocal residence).
Jacob's time with Laban is a mixed tale of hardship, efforts at advancement, and affirmation of kinship. He becomes an indentured servant until he is able to achieve sufficient wealth in livestock to become established in another location. This stirs the jealousy of Laban's sons who say, “Jacob has taken away all that was our father’s, and from what was our father’s he has acquired all this wealth.” (Gen. 31)
Jacob sees that Laban's attitude toward him is no longer favorable, and secretly he flees with his two wives and their households. When Laban discovers that Jacob has left with his daughters and his ancestor figurines (teraphim), he goes after him.
When Laban catches up to Jacob, he asserts his avuncular authority, saying: "It is in my power to do some evil to you, but last night the God of your father told me, 'Be careful what you say to Jacob whether good or evil." (Gen. 31:29)Then Laban asks Jacob, "What did you do? You deceived me, carried off my daughters like you would war captives, ran away from me secretly, and stole from me by not keeping me informed. Otherwise, I could have sent you off with a party and singing, accompanied by a band playing tambourines and harps. As it is, you didn’t even allow me to kiss my grandchildren and daughters goodbye! You’ve acted foolishly." (Gen. 31:26-29)
The story of Jacob and Laban is instructive. As a sent-away son, Jacob poses a threat because sent-away sons seek territories of their own. Laban finally accepts Jacob's departure, assuming that Jacob is returning to his "father's house" (Gen. 31:30). However, Jacob does not remain for long in Esau's territory in ancient Edom. He eventually settles in Shechem where he buys land (Gen. 33:19).
Among Jacob's Hebrew people, royal wives resided in separate settlements. This is evident with Abraham's two wives. Sarah, the half-sister bride, resided in Hebron, and Keturah, the cousin bride, resided in Beersheba. When they came of age, the first-born sons of the cousin brides were sent-away to live among their maternal relatives. The pattern is evident with Rebekah, Isaac's cousin bride, and Jacob, who was sent-away to his maternal uncle.
Godfrey Lienhardt notes the pattern of sent-away sons in the paper cited above. These royal sons are described as "planted out" and "When they are grown, the princes are rivals for the kingship." (p. 30)
Among the Shilluk, the founder of the royal lineage is Dak. Like Esau, he is presented as strong and aggressive, and a mighty hunter of crocodiles. Like Jacob, Dak's half-brother Cal prefers the company of women in the settlement and is less interested in the kingship (op. cit, p. 32).
It appears that the marriage and ascendancy pattern of the biblical Hebrew resembles patterns found among Nilotic royal lineages, and yet it is also distinctive and unique.
