Esau was Isaac and Rebeccaās firstborn son, the twin of Jacob. Already in the womb he struggled against his brother, and in his youth he already showed signs of wickedness. Esau showed his deviation from the ways of God by selling his birthright to Jacob for a bowl of red lentils, earning him the name āEdom,ā meaning red. He went on to marry local pagan girls and become a powerful murderer, adulterer, and thief. Jacob tricked their father, Isaac, who was not aware of Esauās wicked ways, into giving him Esauās blessing. When Esau realized that Jacob got āhisā blessings through trickery, he vowed to kill Jacob, who ran away. Many years later, upon Jacobās return to the Land of Israel, Esau came out to wage war against Jacob but Jacob placated him. Esau then left the Land of Israel and went east to conquer the land of Seir (in modern-day southern Jordan), where he established the kingdom of Edom.
