Short answer: Isaac had two sons, twin brothers named Esau and Jacob, born to Isaac and Rebekah when Isaac was sixty years old (Genesis 25:19–26). Esau came out first, red and hairy, and Jacob followed with his hand holding Esau's heel. Before their birth God told Rebekah that two nations were in her womb and that the elder would serve the younger. The chapter then contrasts the brothers and records Esau selling his birthright to Jacob for a meal and despising it.
The setting and shape of genesis 25:19-34
Genesis 25:19–34 opens with a formal heading, the history of the generations of Isaac, and the narrator immediately narrows the focus. Abraham has died and Ishmael's line has been recorded, so the story turns to the son of promise. Isaac is forty when he marries Rebekah and sixty when the twins arrive. The years are noted plainly, and so is the obstacle: Rebekah is barren. That repeats what happened with Sarah, and it keeps the next generation a matter of God's action rather than human arrangement. The account is prose narrative, moving in order from marriage to prayer to pregnancy to birth to the grown brothers and their bargain.
The shape of the passage carries its meaning. Isaac prays for his wife, God answers, and the pregnancy itself becomes a struggle. Rebekah asks why she lives and goes to inquire of Yahweh, and the answer comes as a short oracle in verse 23, the one poetic line in the chapter. Two nations are in her womb, and the elder will serve the younger. This is said before either child is born or has done anything, so the direction of the whole Jacob story is set by God's choice, not by merit. The oracle explains the conflict; it does not endorse it.
The narrative then turns to the grown sons and the family that raised them. Esau is a hunter of the field, Jacob a quiet man living in tents, and the parents divide: Isaac loves Esau because he eats his venison, Rebekah loves Jacob. That favoritism is reported, not commended, and it will feed the deception and fracture that follow. The bargain over the birthright shows Esau treating a precious inheritance as nothing, and the chapter closes on that verdict. The famine and the move toward Gerar in 26:1–2 continue the same pattern as Abraham's story, keeping Isaac's line dependent on God's guidance.
The birthright traded for stew
The opening line calls this the history of the generations of Isaac, a heading that marks a new section of the book rather than a standalone story. The account then slows down to name Isaac's age at marriage, the years of waiting, and the prayer he prayed because Rebekah was barren. The text says plainly that Yahweh was entreated by him, and she conceived. Before the twins are born, God tells Rebekah that two nations are in her womb and that the elder will serve the younger. The choice is announced before either child has done anything, which shapes how the rest of the chapter should be read.
The births carry the names. The first comes out red and hairy, and they call him Esau. The second follows with his hand holding Esau's heel, and he is named Jacob, a name the text ties to the heel. Later, when Esau asks for the red stew, the narrator adds that his name was called Edom, tying him to the red. The boys grow into different men: Esau a skillful hunter of the field, Jacob a quiet man living in tents. The text also records that Isaac loved Esau because he ate his venison, while Rebekah loved Jacob, a split the story does not commend.
The word birthright means the firstborn's place and inheritance, the right Esau traded away. Famished from the field, he asks for stew; Jacob answers, first sell me your birthright. Esau reasons that he is about to die and asks what good the birthright is to him. He swears, eats, drinks, rises, and goes his way. The narrator's closing verdict is plain: Esau despised his birthright. Nothing here justifies favoritism between siblings, and God's earlier word to Rebekah does not license Jacob's bargaining. The choice is God's; the deceit and the disregard are the brothers' own.
Isaac's sons: esau and Jacob, the twins born to rebekah
The question has a plain answer in this passage. Isaac's sons were twins, Esau and Jacob, born to Isaac and Rebekah. Isaac was forty when he married her and sixty when the boys were born, so the account spans twenty years of waiting. Rebekah was barren, and Isaac pleaded with Yahweh for her, and she conceived. That detail matters because it repeats what happened with Sarah: the next generation comes by God's action, not by human arrangement. The verses just before record Abraham's death and Ishmael's line, so the focus narrows to the son of promise. The twins are not an accident of timing but the answer to prayer.
Before the birth, Rebekah felt the children struggling and went to inquire of Yahweh. The answer she received set the direction for everything after: two nations were in her womb, the one stronger, and the elder would serve the younger. That word came before either boy had done anything, which keeps the choice God's and not a reward for conduct. Esau came out first, red and hairy, and Jacob followed with his hand on Esau's heel. The names fit the moment. Yet the oracle does not make one brother righteous and the other wicked; it announces what God will do, and the story that follows tests both men.
The account then shows what each son became. Esau was a skillful hunter, a man of the field, and Isaac loved him because he ate his venison; Rebekah loved Jacob. That favoritism is described, not endorsed, and it feeds the fracture ahead. One day Esau came in famished and asked for the red stew. Jacob demanded the birthright first, Esau swore, and he sold it for bread and lentils, then rose and went his way. The verdict is that Esau despised his birthright. God's choice of Jacob does not excuse Jacob's scheming, and the passage never treats it as a model to copy.
Where readers disagree about isaac's sons
The bargain in 25:29–34 is where readers part ways. Some point out that the sale was formal: Jacob demanded an oath, Esau swore, and the birthright changed hands. On that reading it was a legal transaction between consenting adults. Others read the same scene and see Jacob as grasping, using his brother's hunger as leverage. The narrator does not settle it by praising Jacob. He closes the account by saying Esau despised his birthright, which is a verdict on Esau, not an endorsement of Jacob. Nothing in the text commends either man's heart, and using this story to justify rivalry or deceit in a family reads against the grain of the passage.
The oracle in 25:23 is disputed differently. Two nations are in the womb, and two peoples will be separated from her body, which suggests the descendants of each son and the later history of Israel and Edom. Yet the wording also touches the brothers themselves: the elder will serve the younger. Some read it as a statement about national destinies, others as a word about the men, and many hold both together. What the text does not say is that God's choice rested on anything either twin had done. The purpose was announced before birth, before any deed, and it is God's purpose rather than their merit that stands.
Readers also weigh whether the sold birthright is the decisive act of unbelief or one episode in a longer pattern. Esau's later marriages and the loss of the blessing belong to the same story, so some treat the stew as a single foolish moment and others as a symptom. Isaac's favoritism toward Esau and Rebekah's toward Jacob are reported plainly, not approved. The passage gives no permission to play favorites among children or to claim God's purposes as cover for manipulation. What stays central is that God's word to Rebekah stood, and that Esau's contempt for his birthright is stated by the narrator without excuse.
The promise carried through an unlikely family
Rebekah was barren, and Isaac prayed for her. The text says plainly that Yahweh was entreated by him, and she conceived. Before the twins are born, God tells her that two nations are in her womb and that the elder will serve the younger. Nothing in the passage says God chose Jacob because of anything Jacob had done. The promise runs through a younger son, in a family where the father favors one child and the mother favors the other. That is the kind of line God keeps moving forward, and it is the same logic the gospel uses: salvation rests on God's call, not on human fitness.
The birthright scene is ugly on both sides. Esau comes in famished and asks for the red stew; Jacob answers by demanding the birthright first, then makes him swear. Esau trades away his standing as firstborn for a single meal, and the chapter closes by saying he despised it. The passage does not praise Jacob's bargaining or excuse Esau's contempt. It shows what it looks like to treat a lasting inheritance as worth less than an immediate appetite. The New Testament later holds Esau up as a warning, and the contrast is clear: the inheritance God gives is not something to be traded for what is on the table today.
God's choice of Jacob does not license the deceit and favoritism that fill this household. The text reports the rivalry between the parents and the scheming between the brothers without approving either. What stays central is that God carries his promise through a flawed family toward the nation of Israel and, in time, toward Christ. The line of promise moves forward because God is faithful, not because these people deserve it. That is where the passage points: a God who keeps his word through unlikely people, and an inheritance too valuable to sell.
What faithful response looks like in ordinary life
Read the account as a warning before you read it as a promise. Esau's hunger was real; the text says he came in from the field famished. But the sale was his own decision. Jacob demanded the birthright before offering a bowl of stew, and Esau swore an oath and traded away his place as firstborn for immediate relief. The last verse names the act plainly: he despised his birthright. Sacred things can be set aside for something as ordinary as lunch. Faithful response begins with honesty about what we are willing to trade away when we are tired, hungry or pressed, and with the choice to wait rather than sell.
Notice also when the promise was spoken. Before either boy had done anything, God told Rebekah that two nations were in her womb and that the elder would serve the younger. That timing matters. It frees readers from measuring their standing by family favor or personal advantage, and it keeps the story from becoming a license for Jacob's scheming or for playing one child against another. Parents and families can name the favoritism in this household honestly, since Isaac loved Esau for his venison and Rebekah loved Jacob, and resist the same pattern in their own homes. God's purpose does not depend on our rivalry.
Grace comes first here. Both brothers fail, one by despising and one by scheming, and the promise survives by God's faithfulness rather than theirs. So pray as Isaac did, asking God for what only he can give, and leave outcomes to him. Then act in ordinary ways: refuse to trade a sacred trust for relief that lasts an afternoon, speak honestly about favoritism in your family, and treat the people in your home as persons rather than as advantages. None of this earns the promise. It is the grateful response of people who know the promise holds even when they stumble.
Biblical fidelity check
This passage was read as a continuous narrative, not as isolated verses. The opening line marks a new section in the book, so the twins' story belongs to the history of Isaac, not to a free-standing tale. The names carry weight: Jacob is tied to the heel he grasped, Edom to the red stew Esau asked for, and the birthright means the firstborn's place and inheritance. The narrator's closing verdict, that Esau despised his birthright, was allowed to stand as the passage's own judgment rather than being softened.
Careful evangelical readers differ over Jacob's conduct in the bargain. Some treat the sale as a legitimate transaction because Esau swore to it; others judge Jacob as grasping and Esau as profane, and the text commends neither man's heart. Readers also differ on whether the oracle about the elder serving the younger concerns the nations, the brothers personally, or both. What stays central is that God's purpose for the line of promise stood before the twins were born and did not rest on their merit, and that Esau's contempt is stated plainly.
Where Genesis 25:19-34 connects to the rest of Scripture
For further study, compare this account with Genesis 10: Nations and Generations After the Flood on Esau's later loss of blessing, Genesis 11: Babel, Shem, and Terah on Jacob's journey and family, Genesis 12: God Calls Abram and Promises Blessing on the promise to Abraham's line, and Genesis 13: Abram and Lot Separate on how the prophets later speak of Jacob and Esau.
Frequently asked questions
How many sons did Isaac have and what were their names?
Isaac had two sons, twins named Esau and Jacob. Genesis 25:24–26 records that when Rebekah's time came, there were twins in her womb: the first came out red and hairy and was named Esau, and his brother followed holding Esau's heel and was named Jacob. Isaac was sixty years old when they were born. The passage gives no other sons to Isaac and Rebekah in this account.
Why did Esau sell his birthright to Jacob?
Esau sold his birthright because he came in from the field famished and wanted the red stew Jacob had boiled. When Jacob asked him to sell the birthright first, Esau said he was about to die and asked what good the birthright was to him. He swore to Jacob and sold it, then ate, drank, rose up and went his way. The chapter closes by saying Esau despised his birthright, which frames the sale as a matter of what Esau valued, not simply hunger.
What did God tell Rebekah about her twin sons before they were born?
God told Rebekah that two nations were in her womb and that two peoples would be separated from her body. He said one people would be stronger than the other and that the elder would serve the younger (Genesis 25:23). This came after the children struggled within her and she went to inquire of Yahweh. The statement is about nations and peoples, not merely two individuals, and it sets the direction for what follows in the account.
