C: The correct answer is David rebuked Abner for negligence and derliction of duty. 1 Samuel 26, David had the opportunity to kill King Saul while he was sleeping in the camp. However, chose not to harm Saul, recognizing him as the Lord's anointed king. Instead, David, accompanied by his nephew Abishai, snuck into Saul's camp while. he and his army were asleep. David took Saul's spear and the jar of water that was beside his head as proof that he could have killed him but chose not to. After leaving the camp, David stood on a hill opposite Saul's camp and called out to Saul's army and to Abner, Saul's commander, rebuking them for their failure to protect the king.
