2 Samuel 15:5-13

5And it was so, that when any man came nigh to him to do him obeisance, he put forth his hand, and took him, and kissed him. 6And on this manner did Absalom to all Israel that came to the king for judgment: so Absalom stole the hearts of the men of Israel.

7And it came to pass after forty years, that Absalom said unto the king, I pray thee, let me go and pay my vow, which I have vowed unto Yhwh, in Hebron. 8For thy servant vowed a vow while I abode at Geshur in Syria, saying, If Yhwh shall bring me again indeed to Jerusalem, then I will serve Yhwh. 9And the king said unto him, Go in peace. So he arose, and went to Hebron.

10But Absalom sent spies throughout all the tribes of Israel, saying, As soon as ye hear the sound of the trumpet, then ye shall say, Absalom reigneth in Hebron. 11And with Absalom went two hundred men out of Jerusalem, that were called; and they went in their simplicity, and they knew not any thing. 12And Absalom sent for Ahithophel the Gilonite, David’s counsellor, from his city, even from Giloh, while he offered sacrifices. And the conspiracy was strong; for the people increased continually with Absalom.

13And there came a messenger to David, saying, The hearts of the men of Israel are after Absalom.
