"Esau accosted Jacob thus, "Why art thou preparing lentils?" Jacob: "Because our grandfather passed away; they shall be a sign of my grief and mourning, that he may love me in the days to come." Esau: "Thou fool! Dost thou really think it possible that man should come to life again after he has been dead and has mouldered in the grave?" He continued to taunt Jacob. "Why dost thou give thyself so much trouble?" he said. "Lift up thine eyes, and thou wilt see that all men eat whatever comes to hand--fish, creeping and crawling creatures, swine's flesh, and all sorts of things like these, and thou vexest thyself about a dish of lentils." Jacob: "If we act like other men, what shall we do on the day of the Lord, the day on which the pious will receive their reward, when a herald will proclaim: Where is He that weigheth the deeds of men, where is He that counteth?" Esau: "Is there a future world? Or will the dead be called back to life? If it were so, why hath not Adam returned? Hast thou heard that Noah, through whom the world was raised anew, hath reappeared? Yea, Abraham, the friend of God, more beloved of Him than any man, hath he come to life again?" Jacob: "If thou art of opinion that there is no future world, and that the dead do not rise to new life, then why dost thou want thy birthright? Sell it to me, now, while it is yet possible to do so. Once the Torah is revealed, it cannot be done. Verily, there is a future world, in which the righteous receive their reward. I tell thee this, lest thou say later I deceived thee.""
