Genesis 23:2

2Sarah died in Kiriath-arba 23:2 This comment indicates that the text was written at a very early date, before Israel entered the promised land, because afterward Hebron was well known. Not only was it conspicuous in Joshua’s and Caleb’s day, but it became a “city of refuge.” Besides all this, David was king in Hebron for seven years.(that is, Hebron) in the land of Canaan, and Abraham went to mourn for Sarah and to weep for her.
