« When Jacob and Esau were in the womb of their mother Jacob, said to Esau, ‘Two worlds are before us, this world and the world to come. In this world we can eat, drink, trade, take a wife, father children, in the world to come none of these standards apply. Do you want to take this world and abandon the world to come to me?’ According to the scripture saying » Sell me your birthright this day « (Gen 35, 31). At this hour, while they were in their mother’s womb, Esau immediately denied the resurrection of the dead, exclaiming: « Behold, I am going to die! What good is the birthright for me! « So Esau took his share in this world while Jacob awaits his reward in the world to come. »
