2 Samuel 15:10-12

15:10 Then Absalom sent spies through all the tribes of Israel who said, “When you hear the sound of the horn, you may assume that Absalom rules in Hebron.” 15:11 Now two hundred men had gone with Absalom from Jerusalem. Since they were invited, they went naively and were unaware of what Absalom was planning. 15:12 While he was offering sacrifices, Absalom sent for Ahithophel the Gilonite, David’s adviser, to come from his city, Giloh. The conspiracy was gaining momentum, and the people were starting to side with Absalom.
