Keturah in the Bible

Now Abraham had taken another wife, whose name was Keturah,

And Midian’s sons were Ephah, Epher, Hanoch, Abida, and Eldaah. All these were sons of Keturah.

but to the sons of his concubines [Hagar and Keturah], Abraham gave gifts while he was still living and he sent them to the east country, away from Isaac his son [of promise].

And, the sons of Keturah, the concubine of Abraham, she bare Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah, - and, the sons of Jokshan, Sheba, and Dedan;

and, the sons of Midian, Ephah, and Epher, and Hanoch, and Abida, and Eldaah. All these, were the sons of Keturah.
