Genesis 25:3-7

Jokshan fathered Sheba and Dedan. And the sons of Dedan were Asshurim, Letushim, and Leummim.

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

Now Abraham gave all that he had to Isaac;

but to the sons of his concubines, Abraham gave gifts while he was still living, and sent them away from his son Isaac eastward, to the land of the east.

These are all the years of Abraham’s life that he lived, 175 years.
