Genesis 25:1-6 Young's Literal Translation (YLT)
25 And Abraham addeth and taketh a wife, and her name [is] Keturah;
2 and she beareth to him Zimran, and Jokshan, and Medan, and Midian, and Ishbak, and Shuah.
3 And Jokshan hath begotten Sheba and Dedan; and the sons of Dedan were Asshurim, and Letushim, and Leummim;
4 and the sons of Midian [are] Ephah, and Epher, and Hanoch, and Abidah, and Eldaah: all these [are] sons of Keturah.
5 And Abraham giveth all that he hath to Isaac;
6 and to the sons of the concubines whom Abraham hath, Abraham hath given gifts, and sendeth them away from Isaac his son (in his being yet alive) eastward, unto the east country.
