2 Samuel 16:8

All the blood of the house of Saul - Shimei probably put to David’s account the death of Saul, and Jonathan, and Abinadab, and Melchishua, slain in battle by the Philistines with whom David was in league; of Ish-bosheth, slain in consequence of David’s league with Abner; that of Abner himself, which he attributed to David’s secret orders; and all the 360 slain in the battle between Joab and Abner 2 Samuel 2:31. Some, too, think that the death of seven men of Saul’s immediate family 2 Samuel 21:8 had occurred before David’s flight, and was referred to by Shimei. Shimei’s hatred and virulence is an indication that the Benjamites resented the loss of royalty in their tribe, even in the palmiest days of David’s monarchy.
