Genesis 23:2

(2) Kirjath-arba; the same is Hebron.—This was a very ancient city, built seven years before Zoan in Egypt (Numbers 13:22), probably by a tribe of Semites on their way to the Delta. It lies upon the very border of the Negeb of Judah, about twenty-two miles south of Jerusalem. Originally it was named Kirjath-arba, and though Arba is called “the father of Anak” (Joshua 15:13), yet the literal meaning City of Four (arba being the Hebrew numeral four), coupled with the fact that Hebron means alliance (Genesis 13:18), suggests that its building was the result of the union of four families; and afterwards, from the name of the city, Arba may have been often used as a proper name. At the conquest of Palestine there were descendants of Anak still dwelling there, and apparently they had restored the old title, but were expelled by Caleb (Joshua 15:14), who took it as his possession, and seems to have given its name to a grandchild, as a memorial of his victory (1 Chronicles 2:42). It is still an important town, with a population of 17,000 Moslems and about 600 Jews.

Abraham came to mourn.—At this period Abraham was in quiet possession of several headquarters, and apparently was himself at Beer-sheba when Sarah died at Hebron, where probably he had left Isaac in charge of his mother and the cattle.
