What does Genesis 23:2 mean?

Abraham's wife Sarah dies in a place called Kiriath-arba, later known to the Israelites as Hebron. Previously, they had been living in Beersheba. Hebron is located between Beersheba and Jerusalem, about 20 miles south of Jerusalem, close to Mamre.

Abraham went in to the place where Sarah's body was located, to mourn and to weep for her. In addition to expressing his great sorrow, Abraham may also have followed the traditions for mourning the dead that would have included the tearing of garments, rubbing of ashes, and fasting.

The marriage of Abraham and Sarah, as recorded in Genesis, has revealed the strengths and weaknesses of both. As such, it rings true to marriage in any era. It's not surprising to find Abraham mourning the loss of his wife so deeply.
