"And he called Esau his elder son" (Genesis 27:1). The night of Passover arrived. Isaac called Esau his son and said to him: My son, this night the heavenly ones recite song; this night the storehouses of dews are opened. Make me savory food. But the Holy Spirit answers him, "Do not eat the bread of one with a grudging eye, nor desire his delicacies" (Proverbs 23:6). And he was delayed there. Rebekah said to Jacob her son: This night the heavenly ones recite song, and so forth; this day is the blessing of the dews. Make savory food for your father, that while he is still in his world he may bless you. "And bring me two kids of the goats" (Genesis 27:9). Now, were two kids of the goats the food of Isaac? Rather, one he offered as the Passover sacrifice, and one he made into savory food. Ten blessings did Isaac bless Jacob, corresponding to the ten utterances by which the world was created. And when Jacob went out, crowned like a bridegroom and like a bride in her ornaments, the reviving dew came down upon him from heaven, and his bones were made hearty, and he became a mighty man of valor. Therefore it is said, "From the hands of the Mighty One of Jacob" (Genesis 49:24).
The Passover Night When Isaac Sent Esau to Hunt
