Esau in Wikipedia
According to the Book of Genesis of the Hebrew Bible, Esau
(pronounced /ˈiːsɔː/) (Hebrew עֵשָׂו, Standard Hebrew Esav,
Tiberian Hebrew ʿĒśāw; Greek: Ἡσαῦ) was the fraternal twin
brother[1][2][3] of Jacob (whom God renamed Israel)-the
patriarch and founder of the Israelites.[4] Esau and Jacob
were the sons of Isaac and Rebekah, and the grandsons of
Abraham and Sarah. Esau was born first and when Jacob was
born, he held onto Esau's heel (Genesis 25:26 ). Isaac was
sixty years old when they were born, but Rebekah is believed
to have been much younger. Abraham was still alive at that
time, though he would have been 160 years old by that stage,
and would live another fifteen years.
As the first born, Esau was entitled to inherit the wealth of
his father Isaac after his death. However, he sold his
birthright to Jacob[4] in exchange for a "mess of pottage"
(meal of lentils) (Genesis 25:29–34 ). According to the
Talmud, the sale of the birthright took place immediately
after Abraham died.[5] The Talmudic dating would give both
Esau and Jacob an age of 15 at the time...
