Genesis 23:2

“And Sarah died in Kirjatharba, etc.] Which was so called, either, as Jarchi says, from the four Anakims or giants that dwelt here, (<061513>Joshua 15:13); or else, as the same writer observes, from the four couple buried here, Adam and Eve, Abraham and Sarah, Isaac and Rebekah, Jacob and Leah; but then it must be so called by anticipation; rather, as Aben Ezra thinks, it had its name from Arba, a great man among the Anakims, and the father of Anak, (<061415>Joshua 14:15); though some take it to be a Tetrapolls, a city consisting of four parts; but be it as it will, here Abraham and Sarah were at the time of her death; when they removed from Beersheba hither is not said: the same [is] Hebron,…”

“Abraham came to mourn for Sarah, &c.--He came from his own tent to take his station at the door of Sarah's. The "mourning" describes his conformity to the customary usage of sitting on the ground for a time; while the "weeping" indicates the natural outburst of his sorrow.”
