Genesis 22:19-24 meaning

Abraham, Isaac, and the two young men arose and returned to Beersheba where they lived. We are told that Abraham lived at Beersheba. This probably means he continued to live there. Beersheba is in southern Israel, it is still called that to this day. It means "well of seven" or "well of the oath." In modern Beersheba there is a traditional location for the well of Genesis 21:31 over which Abraham swore an oath.

Now it came about after these things, after the journey to Mt. Moriah and God sparing Isaac, that Abraham receives information of his brother's lineage. It was told to Abraham that his sister-in-law Milcah also has borne children to his brother Nahor. Uz his firstborn, Buz his brother, Kemuel, Chesed, Hazo, Pildash, Jidlaph, and Bethuel. It is repeated that these eight Milcah bore to Nahor, Abraham's brother.

Abraham's brother Nahor also fathered children with his concubine, whose name was Reumah. She bore Tebah, Gaham, Tahash, and Maacah.

It should be noted that Abraham's brother Nahor had 12 sons, as did Ishmael (Genesis 25:12-16), just as Abraham's grandson Jacob would have 12 sons, the fathers of the 12 tribes of Israel (Israel is the name God gives to Jacob).

We are told a little more information about the family tree, that Nahor's son, Abraham's nephew Kemuel was the father of Aram, and more importantly, that Nabor's son Bethuel became the father of Rebekah. This is likely why this lineage is mentioned. Rebekah would grow up to be Isaac's wife; that account is told in Genesis 24.
