Sarah was an hundred, &c.— It has been observed, that Sarah is the only woman whose entire age is recorded in Scripture. She died in Kirjath-arba, or the city of Arba. It is the same which was afterwards called Hebron. Kirjath-arba signifying properly "the city of four;" the Jews will have it to be so called, because Adam, Abraham, Isaac, and Jacob were buried there. But it is more reasonable to suppose, from Judges 14:15 that it had its name from Arbah, the father of the Anakims.
