Mutuality

15 And at the death of Isaac, he left his cattle and his possessions and all belonging to him to his sons; and Esau said unto Jacob, Behold I pray thee, all that our father has left we will divide it in two parts, and I will have the choice, and Jacob said, We will do so.
16 And Jacob took all that Isaac had left in the land of Canaan, the cattle and the property, and he placed them in two parts before Esau and his sons, and he said unto Esau, Behold all this is before thee, choose thou unto thyself the half which thou wilt take.
17 And Jacob said unto Esau, Hear thou I pray thee what I will speak unto thee, saying, The Lord God of heaven and earth spoke unto our fathers Abraham and Isaac, saying, Unto thy seed will I give this land for an inheritance forever.
18 Now therefore all that our father has left is before thee, and behold all the land is before thee; choose thou from them what thou desirest.
19 If thou desirest the whole land take it for thee and thy children forever, and I will take this riches, and it thou desirest the riches take it unto thee, and I will take this land for me and for my children to inherit it forever.
20 And Nebayoth, the son of Ishmael, was then in the land with his children, and Esau went on that day and consulted with him, saying.
21 Thus has Jacob spoken unto me, and thus has he answered me, now give thy advice and we will hear.
22 And Nebayoth said, What is this that Jacob hath spoken unto thee? Behold all the children of Canaan are dwelling securely in their land, and Jacob sayeth he will inherit it with his seed all the days.
23 Go now therefore and take all thy father’s riches and leave Jacob thy brother in the land, as he has spoken.
24 And Esau rose up and returned to Jacob, and did all that Nebayoth the son of Ishmael had advised; and Esau took all the riches that Isaac had left, the souls, the beasts, the cattle and the property, and all the riches; he gave nothing to his brother Jacob; and Jacob took all the land of Canaan, from the brook of Egypt unto the river Euphrates, and he took it for an everlasting possession, and for his children and for his seed after him forever.
25 Jacob also took from his brother Esau the cave of Machpelah, which is in Hebron, which Abraham had bought from Ephron for a possession of a burial place for him and his seed forever.
26 And Jacob wrote all these things in the book of purchase, and he signed it, and he testified all this with four faithful witnesses.
27 And these are the words which Jacob wrote in the book, saying: The land of Canaan and all the cities of the Hittites, the Hivites, the Jebusites, the Amorites, the Perizzites, and the Gergashites, all the seven nations from the river of Egypt unto the river Euphrates.
28 And the city of Hebron Kireath-arba, and the cave which is in it, the whole did Jacob buy from his brother Esau for value, for a possession and for an inheritance for his seed after him forever.
29 And Jacob took the book of purchase and the signature, the command and the statutes and the revealed book, and he placed them in an earthen vessel in order that they should remain for a long time, and he delivered them into the hands of his children.
30 Esau took all that his father had left him after his death from his brother Jacob, and he took all the property, from man and beast, camel and ass, ox and lamb, silver and gold, stones and bdellium, and all the riches which had belonged to Isaac the son of Abraham; there was nothing left which Esau did not take unto himself, from all that Isaac had left after his death.
