The son of Isaac, and twin brother of Jacob, Genesis 25:1-34. He was the elder of the two, and was therefore legally the heir, but sold his birthright to Jacob. We have an account of his ill-advised marriages, Genesis 26:34; of his loss of his father’s chief blessing, and his consequent anger against Jacob, Genesis 27:1-46; of their subsequent reconciliation, Genesis 32:1-33:20; and of his posterity, Genesis 36:1-43. He is also called Edom; and settled in the mountains south of the Dead Sea, extending to the gulf of Akaba, where he became very powerful. This country was called from him the land of Edom, and afterwards IDUMAEA, which see.
