Joab also and Abishai pursued after Abner,.... Or rather but Joab, &c. They stood not still as the rest, but, filled with indignation and resentment, pursued after Abner, to be avenged on him:and the sun went down when they came to the hill of Ammah; a hill by the side of which was a pool of water, as Kimchi thinks, and from thence so called:that [lieth] before Giah; a place near Gibeon, but nowhere after mentioned:by the way of the wilderness of Gibeon; very likely not far from the city from which it had its name.
