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 elder son, and said unto him: ‘My son’; and he said unto him: ‘Here am I.’ And he said: ‘Behold now, I am old, I know not the day of my death. Now therefore take, I pray thee, thy weapons, thy quiver and thy bow, and go out to the field, and take me venison; and make me savoury food, such as I love, and bring it to me, that I may eat; that my soul may bless thee before I die.’ … 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.’ … 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. … 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. And he also made savoury food, and brought it unto his father; and he said unto his father: ‘Let my father arise, and eat of his son’s venison, that thy soul may bless me.’ … And Isaac trembled very exceedingly, and said: ‘Who then 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 27:1–4, 19, 25, 30–31, 33)

(בראשית כ"ז, א-לג)

Why does Isaac make the blessing conditional on preparing delicacies? Why does he need them?

Elsewhere in the Bible blessings require no delicacies. Jacob blesses Ephraim and Manasseh, his sons before his death, and Joseph, all without a festive meal. Even Isaac himself blesses Jacob without a special meal when sending him to Haran.

Perhaps Isaac’s request of Esau reflects their personal, emotional bond. Isaac loves Esau “because he did eat of his venison” (Genesis 25:28). He loves the food his son prepares, the product of his hunting and culinary skills, which becomes a means to strengthen their bond before the significant moment of blessing.

There may also be a deeper layer. Isaac does not convey firm conviction about choosing Esau over Jacob. He requests food to satisfy his soul – “that my soul may bless thee” (Genesis 27:4) – as though needing encouragement to bless wholeheartedly. This is even more striking afterward, when Jacob proves to have received the blessing and Isaac accepts it unquestioningly: “yea, and he shall be blessed.” Deep inside, Isaac apparently was not wholly certain about blessing Esau rather than Jacob. He may have experienced cognitive dissonance, a conflict between one wish and a hesitant inner voice, and the meal was meant to ease his uncertainty.

Isaac’s need for a meal of rapprochement to overcome conflict is not new. It appears earlier in his covenant with Abimelech and Phicol, his army commander. Isaac initially resists their visit: “Wherefore are ye come unto me, seeing ye hate me, and have sent me away from you?” (Genesis 26:27). After they explain their motives, he makes a feast and they eat and drink. Only after the meal and reconciliation, the next morning, do they swear to each other, and Isaac sends them away peacefully.

In Isaac’s blessing, the Torah repeats four times that it is his soul’s blessing. “That my soul may bless thee” is no ordinary biblical formula. Usually the person himself blesses; his “soul” does not.

The story seems to emphasize a deeper inner level expressing the person’s true wish – the nefesh, “soul.” Similarly Abraham tells the Hittites: “If it be your mind that I should bury my dead out of my sight” (Genesis 23:8). The Hebrew says “if it is your nefesh”: if you truly wish to let me bury Sarah.

To awaken his soul, his deepest inner wish, Isaac asks Esau for delicacies. These are a deliberate means of opening the heart so the soul can act, rather than an indulgence. His soul apparently requires a special state of inner calm to express its will.

Isaac’s soul is presented as an entity in its own right, an inner layer distinct from conscious Isaac. At the blessing, this deeper personality layer blesses, acting according to his true wish rather than what he thinks or intends. The soul has its own dynamics, the hidden “I” within a person, and it blesses instead of conscious Isaac.

Conscious Isaac still wonders whether this is Jacob or Esau, but the soul knows. Distinguishing Isaac from his soul creates space for the blessing to exist beyond his explicit intentions and reflect the inner wish below consciousness’s threshold.

Perhaps this emphasis provides the whole story’s key. Isaac can accept the result as revealing his own inner truth, rather than as an arbitrary decree forced upon him. The revelation makes him tremble exceedingly; precisely because his own soul decided who would bear the blessing, he accepts its decision without reservation: “yea, and he shall be blessed.”
