Genesis 25:29-34
29 Once when Jacob was cooking some stew, Esau came in from the open country, famished. 30 He said to Jacob, "Quick, let me have some of that red stew! I'm famished!" (That is why he was also called Edom.)
31 Jacob replied, "First sell me your birthright."
32 "Look, I am about to die," Esau said. "What good is the birthright to me?"
33 But Jacob said, "Swear to me first." So he swore an oath to him, selling his birthright to Jacob.
34 Then Jacob gave Esau some bread and some lentil stew. He ate and drank, and then got up and left.
So Esau despised his birthright.
Esau gave away his 'birthright' as the first born male for a bow of lentils (red stew). Jacob, however, did not buy it but tricked his father Isaac into bestowing it upon him.
The first born son of a married couple
Esau was the firstborn child of Isaac and Rebekah. He had a twin brother Jacob who was born right after him. The Bible chronicles that he didn't appreciate "his birthright" and traded it to his brother Jacob for a bowl of red stew.
Genesis 25 records that Esau sold his birthright to Jacob in exchange for a meal. 29And Jacob sod pottage: and Esau came from the field, and he was faint: 30And Esau said to Jacob, Feed me, I pray thee, with that same red pottage; for I am faint: therefore was his name called Edom. 31And Jacob said, Sell me this day thy birthright. 32And Esau said, Behold, I am at the point to die: and what profit shall this birthright do to me? 33And Jacob said, Swear to me this day; and he sware unto him: and he sold his birthright unto Jacob. 34Then Jacob gave Esau bread and pottage of lentiles; and he did eat and drink, and rose up, and went his way: thus Esau despised his birthright.
It means obtaining that which is due to him by right of his birth. A birthright is a right bestowed upon someone simply by them being born a specific person. For example, the son of a king is born as a prince. It is his birthright to be a prince simply because he was born the son of a king. Taking this example a little further, the first born son of a king will likely become king himself one day (as traditionally this honour passes to the first born male). When he becomes king he could describe this as "coming into his birthright".
Reuben was the eldest son of Jacob and Leah. He lost his birthright to Joseph(The first born son of Jacob and Rachel) and it was Joseph who received the blessing from Jacob, which should have gone to Reuben. Reuben became an enemy of Joseph for many years but finally made up. The tribe of Reuben became of less importance politically, and its members became less as the years went by.
Esau, and potentially others Referencing Old Testament: Genesis Chapter 25 New Testament: Hebrews 12:14 - 17; Philippians 3:19; Romans 16:18 Esau was the eldest of twins born to the Biblical patriarch, Isaac. The younger twin was named Jacob. When Esau was faint with hunger upon return home from the field, he asked Jacob for some of the stew Jacob had prepared. Jacob offered to sell it for Esau's birthright as the elder brother. Esau basically said the birthright would not do him any good if he was dead of hunger. He " sware unto him: and he sold his birthright unto Jacob. Then Jacob gave Esau bread and pottage of lentiles; and did eat and drink, and rose up, and went his way: thus Esau despised his birthright." Hebrews 12:14-17 "Follow peace with all men, and holiness, without which no man shall see the Lord: Looking diligently lest any man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled: Lest there be any fornicator, or godless person, as Esau, who for one morsel of bread sold his birthright. For ye know that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears." The persons whose actions and attitudes are documented in the Old Testament are types and shadows of those to come. Question asked by God: Would you be as Esau and trade your birthright for a morsel of bread? According to John Chapter 1 and Chapter 3, and Romans 8:17, we can become the sons of God. We must be born again of the Spirit. Then we become joint heirs with Jesus Christ. Now we too have a birthright. How could we possibly trade our birthright for a morsel of bread? The Bible refers to those whose God is their belly. This is a quick answer but anyone who would choose short term bodily satisfaction over the spiritual riches of God be it for food or sex, etc.after having been born again in Christ Jesus is a potential seller of birthright. As believers in Christ Jesus, Certainly we have been given the ability to overcome sin by the word of our testimony and the blood of the lamb. If we still choose to return to sin, we give up our birthright.
Esau
Esau is the son of Isaac and the twin brother of Jacob. He is born in Genesis chapter 25, but if you keep reading through 27 you'll get more of his story. He is noted to be particularly hairy and a skillful hunter. He traded his birthright to Jacob for some stew, and was cursed by his father after Jacob stole their Isaac's blessing.
Ancient Hebrews practiced a patriarchal order. The "birthright" by tradition belonged to the first-born son and was a type or symbol of the relationship between God and His first-born Son. The inheritance generally included land and a larger portion of flocks and other possessions than other sons would receive. Patriarchal prophets also gave their sons blessings to both pass along the covenants made with Abraham, as well as to provide inspired guidance with respect to their future lives and legacies. In the case of Jacob and Esau, the birthright and the blessing both passed to Jacob even though he was the younger of the twins. The birthright passed to Jacob through the careless act of Esau. Esau was famished after being "in the field" and actually traded away his birthright for a serving of pottage that his brother had made. (Genesis 25:29-34) The blessing was given under different circumstances. With Isaac's eyesight failing, Rebekah was determined that her more spiritual son would receive the blessing. To that end, she clothed Jacob in woolen clothing or skins to hide his "smoothness." She then helped him prepare a meal of venison - Isaac's favorite - and had him present it to Isaac. Isaac then gave the desired blessing to Jacob. When Esau returned and sought the blessing from his father, the deception was discovered. Yet, Isaac knew that the blessing had been given to the deserving individual. Esau had lived in rebellion of certain commandments, and would not have prospered under the blessing apparently intended for Jacob, who would later become Israel and the father of a great nation. (Genesis 27:1-40)
