Sarah died in Kirjath-arba, or city of Arba So called, it seems, from Arba, a giant, who lived and ruled in those parts, Joshua 14:15; Joshua 15:13. Abraham came into Sarah's tent to mourn for Sarah. 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 sustained, and gave proof of the constancy of his affection. Therefore these two words are used, he came both to mourn and to weep.
