Genesis 25:7

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.

7 And these [are] the days of the years of the life of Abraham, which he lived, a hundred and seventy and five years;

8 and Abraham expireth, and dieth in a good old age, aged and satisfied, and is gathered unto his people.

9 And Isaac and Ishmael his sons bury him at the cave of Machpelah, at the field of Ephron, son of Zoar the Hittite, which [is] before Mamre --

10 the field which Abraham bought from the sons of Heth -- there hath Abraham been buried, and Sarah his wife.
