“Ahinoam the Jezreelitess.” This is the “Jezreel” of Judah, not the Jezreel in the Jezreel Valley. This Jezreel is in south-central Judah, not far from Maon, Ziph, and Carmel (cp. Josh. 15:56; 1 Sam. 25:43; 27:3; 30:5; 2 Sam. 2:2; 3:2; see commentary on Josh. 15:56).

“the wife of Nabal the Carmelite.” It is understood in the record that Nabal had died. David was not committing adultery here but the record is pointing out that Abigail had been married before (1 Sam 25:37-42).
