Then again Avraham took a wife, and her name was Keturah.
And Yitzchak called Yaakov, and blessed him, and charged him, and said unto him, Thou shalt not take a wife of the daughters of Kenaan.
And Yitzchak brought her into his mother Sarah's tent, and took Rebekah, and she became his wife; and he loved her: and Yitzchak was comforted after his mother's death.
And she bare him Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah.
