2 Samuel 15:12; 2 Samuel 15:32

12 While Absalom was offering sacrifices, he also sent for Ahithophel the Gilonite, David’s counselor, to come from Giloh, his hometown. And so the conspiracy gained strength, and Absalom’s following kept on increasing.

32 When David arrived at the summit, where people used to worship God, Hushai the Arkite was there to meet him, his robe torn and dust on his head.
