2 Samuel 17:1-4

Furthermore, Ahithophel said to Absalom, “Please let me choose 12,000 men that I may arise and pursue David tonight. I will come upon him while he is weary and exhausted and terrify him, so that all the people who are with him will flee. Then I will strike down the king alone, and I will bring back all the people to you. The return of everyone depends on the man you seek; then all the people will be at peace.” So the plan pleased Absalom and all the elders of Israel.
