Jacob

Jacob in the Bible, a Hebrew patriarch, the younger of the twin sons of Isaac and Rebecca, who persuaded his brother Esau to sell him his birthright and tricked him out of his father's blessing (Genesis 25, 27).

Jacob married his cousin Rachel and (through the deception of their father, his uncle Laban) her sister Leah; it was Rachel's children, his youngest sons Joseph and Benjamin who were dearest to him. His twelve sons became the founders of the twelve tribes of ancient Israel.
Jacob sheep a breed of piebald sheep named originally from the story in Genesis 30:40, in which Jacob, who has herded his uncle Laban's cattle and sheep, is given the speckled and brown animals for his portion.
Jacob's ladder a ladder reaching up to heaven, seen in a dream by Jacob (Genesis 28:12), when he saw the angels of God ascending and descending; it was in the same dream that God spoke to him and promised to him and his descendants the land on which he was then lying. When he woke in the morning he set up the stone which had been his pillow to mark the place, which was later named Bethel.
Jacob's stone a name given to the stone of Scone, said to have been the stone used by Jacob for a pillow when he had the dream of Jacob's ladder.
