Genesis 25:6

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

5And Abraham gave all that he had unto Isaac.

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

7And these are the days of the years of Abraham’s life which he lived, an hundred threescore and fifteen years.

8Then Abraham gave up the ghost, and died in a good old age, an old man, and full of years; and was gathered to his people.
