David and Abishai entered the camp of Saul. David spares Saul's life but takes away from beside him the King's spear and a cruise of water. From a hilltop David calls Abner who leads Saul's army and rebukes him. Saul recognises David's voice, learns of David's mercy and repents of his murderous actions. Learn lessons from David's rebuke of Abner. Learn and consider our own repentance for sin from Saul's words.
