Genesis 23:2

Sarah died in Kirjath-arba - Literally in the city of the four. Some suppose this place was called the city of the four because it was the burial place of Adam, Abraham, Isaac, and Jacob; others, because according to the opinion of the rabbins, Eve was buried there. with Sarah, Rebekah, and Leah. But it seems evidently to have had its name from a Canaanite, one of the Anakim, probably called Arba (for the text, Joshua 14:14, does not actually say this was his name), who was the chief of the four brothers who dwelt there; the names of the others being Sheshai, Ahiman, and Talmai. See Judges 1:10. These three were destroyed by the tribe of Judah; probably the other had been previously dead.

Abraham came to mourn for Sarah - From Genesis 22:19 of the preceding chapter it appears that Abraham had settled at Beer-sheba; and here we find that Sarah died at Hebron, which was about twenty-four miles distant from Beersheba. For the convenience of feeding his numerous flocks, Abraham had probably several places of temporary residence, and particularly one at Beer-sheba, and another at Hebron; and it is likely that while he sojourned at Beersheba, Sarah died at Hebron; and his coming to mourn and weep for her signifies his coming from the former to the latter place on the news of her death.

23:2 Abraham came to mourn for Sarah and to weep - He did not only perform the ceremonies of mourning according to the custom of those times, but did sincerely lament the great loss he had, and gave proof of the constancy of his affection. Therefore these two words are used, he came both to mourn and to weep.
