2 Samuel 15:6-12

6Thus Absalom did to all of Israel who came to the king for judgment. So Absalom stole the hearts of the men of Israel. 7And at the end of four years Absalom said to the king, “Please let me go and pay my vow, which I have vowed to the LORD, in Hebron. 8For your servant vowed a vow while I lived at Geshur in Aram, saying, ‘If the LORD will indeed bring me back to Jerusalem, then I will offer worship to the LORD.’” 9The king said to him, “Go in peace.” So he arose and went to Hebron. 10But Absalom sent secret messengers throughout all the tribes of Israel, saying, “As soon as you hear the sound of the trumpet, then say, ‘Absalom is king at Hebron!’” 11With Absalom went two hundred men from Jerusalem who were invited guests, and they went in their innocence and knew nothing. 12And while Absalom was offering the sacrifices, he sent for Ahithophel the Gilonite, David’s counselor, from his city Giloh. And the conspiracy grew strong, and the people with Absalom kept increasing.
