Isaac is tricked into blessing Jacob as the eldest - giving him Esau's patrimony.

GENESIS 27:1  And it came to pass, that when Isaac was old, and his eyes were dim,  so that he could not see, he called Esau his eldest son, and said unto him,  My son: and he said unto him, Behold, here am I.

GENESIS 27:2  And he said, Behold now, I am old, I know not the day of my death:

GENESIS 27:3  Now therefore take, I pray thee, thy weapons, thy quiver and thy  bow, and go out to the field, and take me some venison;

GENESIS 27:4  And make me savoury meat, such as I love, and bring it to me, that I  may eat; that my soul may bless thee before I die.

GENESIS 27:5  And Rebekah heard when Isaac spake to Esau his son. And Esau went  to the field to hunt for venison, and to bring it.

GENESIS 27:6  And Rebekah spake unto Jacob her son, saying, Behold, I heard thy  father speak unto Esau thy brother, saying,

GENESIS 27:7  Bring me venison, and make me savoury meat, that I may eat, and bless  thee before the LORD before my death.

GENESIS 27:8  Now therefore, my son, obey my voice according to that which I  command thee.

GENESIS 27:9  Go now to the flock, and fetch me from thence two good kids of the  goats; and I will make them savoury meat for thy father, such as he loveth:

GENESIS 27:10  And thou shalt bring it to thy father, that he may eat, and that he  may bless thee before his death.

GENESIS 27:11  And Jacob said to Rebekah his mother, Behold, Esau my brother is a  hairy man, and I am a smooth man:

GENESIS 27:12  My father peradventure will feel me, and I shall seem to him as a  deceiver; and I shall bring a curse upon me, and not a blessing.

GENESIS 27:13  And his mother said unto him, Upon me be thy curse, my son: only  obey my voice, and go fetch me them.

GENESIS 27:14  And he went, and fetched, and brought them to his mother: and his  mother made savoury meat, such as his father loved.

GENESIS 27:15  And Rebekah took goodly raiment of her eldest son Esau, which were  with her in the house, and put them upon Jacob her younger son:

GENESIS 27:16  And she put the skins of the kids of the goats upon his hands, and  upon the smooth of his neck:

GENESIS 27:17  And she gave the savoury meat and the bread, which she had prepared,  into the hand of her son Jacob.

GENESIS 27:18  And he came unto his father, and said, My father: and he said, Here  am I; who art thou, my son?

GENESIS 27:19  And Jacob said unto his father, I am Esau thy first born; I have  done according as thou badest me: arise, I pray thee, sit and eat of my  venison, that thy soul may bless me.

GENESIS 27:20  And Isaac said unto his son, How is it that thou hast found it so  quickly, my son? And he said, Because the LORD thy God brought it to me.

GENESIS 27:21  And Isaac said unto Jacob, Come near, I pray thee, that I may feel  thee, my son, whether thou be my very son Esau or not.

GENESIS 27:22  And Jacob went near unto Isaac his father; and he felt him, and  said, The voice is Jacob's voice, but the hands are the hands of Esau.

GENESIS 27:23  And he discerned him not, because his hands were hairy, as his  brother Esau's hands: so he blessed him.

GENESIS 27:24  And he said, Art thou my very son Esau? And he said, I am.

GENESIS 27:25  And he said, Bring it near to me, and I will eat of my son's  venison, that my soul may bless thee. And he brought it near to him, and he  did eat: and he brought him wine and he drank.

GENESIS 27:26  And his father Isaac said unto him, Come near now, and kiss me, my  son.

GENESIS 27:27  And he came near, and kissed him: and he smelled the smell of his  raiment, and blessed him, and said, See, the smell of my son is as the smell  of a field which the LORD hath blessed:

GENESIS 27:28  Therefore God give thee of the dew of heaven, and the fatness of the  earth, and plenty of corn and wine:

GENESIS 27:29  Let people serve thee, and nations bow down to thee: be lord over  thy brethren, and let thy mother's sons bow down to thee: cursed be every one  that curseth thee, and blessed be he that blesseth thee.

GENESIS 27:30  And it came to pass, as soon as Isaac had made an end of blessing  Jacob, and Jacob was yet scarce gone out from the presence of Isaac his  father, that Esau his brother came in from his hunting.

GENESIS 27:31  And he also had made savoury meat, and brought it unto his  father, and said unto his father, Let my father arise, and eat of his son's  venison, that thy soul may bless me.

GENESIS 27:32  And Isaac his father said unto him, Who art thou? And he said, I am  thy son, thy firstborn Esau.

GENESIS 27:33  And Isaac trembled very exceedingly, and said, Who? where is he that  hath taken venison, and brought it me, and I have eaten of all before thou  camest, and have blessed him? yea, and he shall be blessed.

GENESIS 27:34  And when Esau heard the words of his father, he cried with a great  and exceeding bitter cry, and said unto his father, Bless me, even me also, O  my father.

GENESIS 27:35  And he said, Thy brother came with subtilty, and hath taken away thy  blessing.

GENESIS 27:36  And he said, Is not he rightly named Jacob? for he hath supplanted  me these two times: he took away my birthright; and, behold, now he hath  taken away my blessing. And he said, Hast thou not reserved a blessing for  me?

GENESIS 27:37  And Isaac answered and said unto Esau, Behold, I have made him thy  lord, and all his brethren have I given to him for servants; and with corn  and wine have I sustained him: and what shall I do now unto thee, my son?

GENESIS 27:38  And Esau said unto his father, Hast thou but one blessing, my  father? bless me, even me also, O my father. And Esau lifted up his  voice, and wept.

GENESIS 27:39  And Isaac his father answered and said unto him, Behold, thy  dwelling shall be the fatness of the earth, and of the dew of heaven from  above;

GENESIS 27:40  And by thy sword shalt thou live, and shalt serve thy brother; and  it shall come to pass when thou shalt have the dominion, that thou shalt  break his yoke from off thy neck.

GENESIS 27:41  And Esau hated Jacob because of the blessing wherewith his father  blessed him: and Esau said in his heart, The days of mourning for my father  are at hand; then will I slay my brother Jacob.

GENESIS 27:42  And these words of Esau her elder son were told to Rebekah: and she  sent and called Jacob her younger son, and said unto him, Behold, thy brother  Esau, as touching thee, doth comfort himself, purposing to kill thee.

GENESIS 27:43  Now therefore, my son, obey my voice; arise, flee thou to Laban my  brother to Haran;

GENESIS 27:44  And tarry with him a few days, until thy brother's fury turn away;

GENESIS 27:45  Until thy brother's anger turn away from thee, and he forget that  which thou hast done to him: then I will send, and fetch thee from thence:  why should I be deprived also of you both in one day?

GENESIS 27:46  And Rebekah said to Isaac, I am weary of my life because of the  daughters of Heth: if Jacob take a wife of the daughters of Heth, such as  these which are of the daughters of the land, what good shall my life do me?
