2 Samuel 17:1-4

Furthermore, Ahithophel said to Absalom, “Please let me choose twelve thousand men and let me set out and pursue David tonight.

And I will attack him while he is weary and exhausted and startle him, so that all the people who are with him will flee. Then I will strike and kill the king when he is alone,

and I will bring all the people back to you. The return of everyone depends on the man whom you are seeking; then all the people will be at peace.”

And the plan pleased Absalom and all the elders of Israel.
