2 Samuel 17:1-4

Then, Ahithophel said to Absalom, “Please let me choose 12,000 men, and I will set out and pursue David tonight. I will strike while he is weary and exhausted, and terrify him; and all the people with him will flee [in terror]. Then I will attack the king alone, and I will bring all the people [who follow David] back to you. The return of everyone depends on the [death of the] man you are seeking; then all the people will be at peace [and accept you as king].” So the plan pleased Absalom and all the elders of Israel.
