Genesis 25:1 Then again Abraham took a wife, and her name was Keturah.
Genesis 25:4 And the sons of Midian; Ephah, and Epher, and Hanoch, and Abida, and Eldaah. All these were the children of Keturah.
1 Chronicles 1:32 Now the sons of Keturah, Abraham’s concubine: she bare Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah. And the sons of Jokshan; Sheba, and Dedan.
Genesis 25:6 But to the sons of his concubines Abraham gave gifts, and while he was still living he sent them away from his son Isaac, eastward to the east country.
