2nd Samuel 15:10

7 And it came to pass at the end of forty years, that Absalom said unto the king, I pray thee, let me go and pay my vow, which I have vowed unto Jehovah, in Hebron.

8 For thy servant vowed a vow while I abode at Geshur in Syria, saying, If Jehovah shall indeed bring me again to Jerusalem, then I will serve Jehovah.

9 And the king said unto him, Go in peace. So he arose, and went to Hebron.

10 But 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 is king in Hebron.

11 And with Absalom went two hundred men out of Jerusalem, that were invited, and went in their simplicity; and they knew not anything.

12 And Absalom sent for Ahithophel the Gilonite, David`s counsellor, from his city, even from Giloh, while he was offering the sacrifices. And the conspiracy was strong; for the people increased continually with Absalom.

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