“Moreover Ahithophel said to Absalom. ‘Let me choose twelve thousand men. I will set out and pursue David tonight. I will come upon him while he is weary and discouraged, and throw him into a panic. All the people who are with him will flee. I will strike down only the king. I will bring all the people back to you as a bride comes home to her husband. You seek the life of only one man. All the people will be at peace.’ The advice pleased Absalom and all the elders of Israel.”
Ahithophel had a nice simple plan. He would take 12,000 men and go after David that night while he was still tired. He would attack David and his people, which would make all of them scatter in a panic. Then Ahithophel would only kill King David. After that all the people would be at peace and only one man would be dead, David. Everyone liked this neat plan where only 1 person died, King David.
