Jacob and Esau - twin sons of Isaac and Rebecca, they struggled in the womb and God said they should be two nations, the elder serving the younger. Esau ("hairy") the first-born, was a hunter; and Jacob ("supplanter"), born clutching his brother's heel, was a farmer. When Esau was starving, he sold his birthright for a mess of Jacob's pottage. When Isaac was old and blind, he sent Esau to hunt and bring him venison. On Rebecca's advice, Jacob (a smooth man) put on a goatskin and carried venison to his father, who said, "The voice is the voice of Jacob, but the hands are the hands of Esau." And Isaac gave Jacob the blessing meant for Esau. To escape his brother's wrath, Jacob went into exile, slept on a stone in Bethel (tradition says, it became the Stone of Destiny or Lia Fail); he dreamt of a ladder reaching up to heaven, wrestled with an angel, and was given a new name, Israel. He married Rachel and Leah.
Genesis 27:19: (Jacob deceiving blind Isaac into blessing him) 'And Jacob said unto his father, I am Esau thy firstborn... sit and eat of my venison, that thy soul may bless me'.
