Chapter 25 of Genesis Brings the Birth of Jacob and Esau

Sarah, Rebecca and Rachel are all barren. But all found favor in the eyes of G-d for their righteousness, modesty and holiness.

Twin brothers Jacob and Esau are caught in situations where their characters are exposed.

“Barrenness and Pregnancy of Rebecca”
“Jacob and Esau are Born”
“The Birthright”

Abraham proceeded and took a wife whose name was Keturah (Hagar).
25:1
Abraham gave all that he had to Isaac.
:5
Now these are the days of the years of Abraham’s life which he lived: a hundred years, seventy years, and five years.
:7
And Abraham expired and died at a good old age, mature and content, and he was gathered to his people.
:8
His sons Isaac and Ishmael buried him in the cave of Machpelah, in the field of Ephron the son of Zohar the Hittite, facing Mamre.
:9
Isaac entreated Hashem opposite his wife, because she was barren. Hashem allowed HImself to be entreated by him, and his wife Rebecca conceived.
:21
And Hashem said to her: “Two nations are in your womb; two regimes from your insides shall be separated; the might shall pass from one regime to the other, and the elder shall serve the younger.”
:23
When her term to bear grew full, then behold! there were twins in her womb.
:24
The first one emerged red, entirely like a hairy mantle; so they named him Esau.
:25
After that his brother emerged with his hand grasping on to the heel of Esau; so he called his name Jacob; Isaac was sixty years old when she bore them.
:26
The lads grew up and Esau became one who knows hunting, a man of the field; but Jacob was a wholesome man, abiding in tents.
:27
Isaac loved Esau for game was in his mouth; but Rebecca loved Jacob.
:28
Esau said to Jacob, “Pour into me, now, some of that very red stuff for I am exhausted.” (He therefore called his name Edom).
:30
Jacob said, “Sell, as this day, your birthright to me.” And Esau said, “Look, I am going to die, so of what use to me is a birthright?”
:30-31
Jacob said, “Swear to me as this day”; he swore to him and sold his birthright to Jacob.
:33
… thus, Esau spurned the birthright.
:34

1 And Abraham took another wife and her name was Keturah.
2 And she bore him Zimran and Jokshan and Medan and Midian and Jishbak and Shuah.
3 And Jokshan begot Sheba and Dedan, and the sons of Dedan were Ashurim, Letushim, and Leumim.
4 And the sons of Midian [were] Ephah and Epher and Enoch and Abida and Elda’ah; all these were the sons of Keturah.
5 And Abraham gave all that he possessed to Isaac.
6 And to the sons of Abraham’s concubines, Abraham gave gifts, and he sent them away from his son Isaac while he [Abraham] was still alive, eastward to the land of the East.
7 And these are the days of the years of Abraham’s life that he lived: one hundred years and seventy years and five years.
8 And Abraham expired and died in a good old age, old and satisfied, and he was gathered to his people.
9 And Isaac and Ishmael his sons buried him in the Cave of Machpelah in the field of Ephron the son of Zohar the Hittite, which faces Mamre,
10 The field that Abraham had bought from the sons of Heth there Abraham and his wife Sarah were buried.
11 Now it came to pass after Abraham’s death, that God blessed his son Isaac, and Isaac dwelt near Be’er Lachai Ro’i.
12 Now these are the generations of Ishmael the son of Abraham, whom Hagar the Egyptian, the maidservant of Sarah, bore to Abraham.
13 And these are the names of the sons of Ishmael by their names, according to their births: the firstborn of Ishmael was Nebaioth, and Kedar and Adbe’el and Mibsam,
14 And Mishma and Dumah and Massa,
15 Hadad and Tema, Jetur, Naphish, and Kedmah.
16 These are the sons of Ishmael, and these are their names in their open cities and in their walled cities, twelve princes to their nations.
17 And these are the years of the life of Ishmael: one hundred years and thirty years and seven years; and he expired and died and was gathered to his people.
18 And they dwelt from Havilah to Shur, which borders on Egypt, going towards Asshur; before all his brothers he dwelt.
19 And these are the generations of Isaac the son of Abraham; Abraham begot Isaac.
20 And Isaac was forty years old when he took Rebecca the daughter of Bethuel the Aramean of Padan Aram, the sister of Laban the Aramean, to himself for a wife.
21 And Isaac prayed to the Lord opposite his wife because she was barren, and the Lord accepted his prayer, and Rebecca his wife conceived.
22 And the children struggled within her, and she said, “If [it be] so, why am I [like] this?” And she went to inquire of the Lord.
23 And the Lord said to her, “Two nations are in your womb, and two kingdoms will separate from your innards, and one kingdom will become mightier than the other kingdom, and the elder will serve the younger.
24 And her days to give birth were completed, and behold, there were twins in her womb.
25 And the first one emerged ruddy; he was completely like a coat of hair, and they named him Esau.
26 And afterwards, his brother emerged, and his hand was grasping Esau’s heel, and he named him Jacob. Now Isaac was sixty years old when she gave birth to them.
27 And the youths grew up, and Esau was a man who understood hunting, a man of the field, whereas Jacob was an innocent man, dwelling in tents.
28 And Isaac loved Esau because [his] game was in his mouth, but Rebecca loved Jacob.
29 Now Jacob cooked a pottage, and Esau came from the field, and he was faint.
30 And Esau said to Jacob, “Pour into [me] some of this red, red [pottage], for I am faint”; he was therefore named Edom.
31 And Jacob said, “Sell me as of this day your birthright.”
32 Esau replied, “Behold, I am going to die; so why do I need this birthright?”
33 And Jacob said, “Swear to me as of this day”; so he swore to him, and he sold his birthright to Jacob.
34 And Jacob gave Esau bread and a pottage of lentils, and he ate and drank and arose and left, and Esau despised the birthright.
