Genesis 25:4 DBY

²  And she bore him Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah.

³  And Jokshan begot Sheba and Dedan; and the sons of Dedan were the Asshurim, and the Letushim, and the Leummim.

⁴  And the sons of Midian were Ephah, and Epher, and Enoch, and Abida, and Eldaah. All these were sons of Keturah.

⁵  And Abraham gave all that he had to Isaac.

⁶  And to the sons of the concubines that Abraham had, Abraham gave gifts, and, while he yet lived, sent them away from Isaac his son, eastward to the east country.
