There are two women in the Bible named Adah. One was a wife of Lamech and the other was married to Esau.
Esau took wives among the women of Canaan, including a woman named Adah, who was the daughter of Elon the Hittite (Gen. 36:2). Adah gave birth to a son named Eliphaz (Gen. 36:4), the firstborn of Esau (Gen. 36:15). Adah's grandsons, through Eliphaz, were chiefs in the land of Edom and their names are listed in Gen. 36:16 as Korah, Gatam and Amalek.
Adah, wife of Esau, is mentioned by name five times in the Bible, in Gen. 36:2, 4, 10, 12, 16.
The name Adah means "adornment," "beauty" or "pleasure."
The other Adah was a wife of Lamech.
