Yes, Esau and Jacob are twins according to the Hebrew Bible. They were the sons of Isaac and Rebekah, and Jacob was born immediately after Esau, grasping his brother's heel at birth—an event that inspired Jacob's name, which means "he grasps the heel" or "supplanter." The biblical account describes them as fraternal twins with notably different appearances and temperaments: Esau is portrayed as a skilled hunter with red skin and hair, while Jacob is described as a quiet man who dwelt in tents. The twins' relationship is central to biblical narrative, marked by rivalry and deception. Jacob tricked Esau into selling his birthright for a bowl of stew, and later deceived their father Isaac to receive the blessing intended for the firstborn. This conflict eventually led to Jacob fleeing his homeland and spending years in exile. The two brothers later reconciled after Jacob's long absence. Their story explores themes of favoritism, ambition, divine providence, and redemption. The rivalry between Jacob and Esau is also interpreted in religious tradition as foreshadowing the relationship between their descendants—the Israelites (Jacob's line) and the Edomites (Esau's line). In Islamic tradition, these figures are also recognized, with Jacob and Esau (called Yaqub and Isa in Arabic) appearing in the Quran as brothers, though the Islamic account differs in some details from the Hebrew biblical version.
