returned to Hebron
2 Samuel 3:27
3:27 returned to Hebron. It was doubly treacherous for Joab and Abishai (II Samuel 3:30) to kill Abner in Hebron, for Hebron was one of the cities of refuge (Joshua 20:2,7), and it was unlawful for an avenger of blood to take vengeance on a man slayer in a city of refuge without a trial.
