Genesis 22:20-21, 23

And it came to pass after these things, that it was told Abraham, saying, Behold, Milcah, she hath also born children unto thy brother Nahor; Huz his firstborn, and Buz his brother, and Kemuel the father of Aram

And Bethuel begat Rebekah: these eight Milcah did bear to Nahor, Abraham's brother.
