the food that Jacob was preparin
Esau was older than Jacob. Esau was born first, with Jacob being his younger twin brother.
Esau
Isaac found out too late that it was Jacob he blessed and not Esau when Esau returned from the hunt and cooked his favorite food. Esau pleaded that he be given another blessing but Isaac said this was not possible. In the face of Esau's wrath, Jacob was sent away by Rebecca to her relatives .
Esau gave away his 'birthright' as the first born male for a bow of lentils (red stew). Jacob, however, did not buy it but tricked his father Isaac into bestowing it upon him.
Esau and Jacob fought over the birthright blessing, which was traditionally given to the firstborn son in their culture. Jacob, the younger brother, tricked Esau into selling him his birthright.
Your are probably referring to Jacob and Esau. They were twins born to Isaac and Rebekah. God chose Jacob to continue the Hebrew (Israel) race and He rejected Esau. Esau became the "father" of the Edomite's. They would be distant cousins of Israel. To read of the fascinating story of Jacob and Esau see Genesis, chapter 27.
