2nd Samuel 15:10

7 Now at the end of four years, Absalom said to the king, Let me go to Hebron and give effect to the oath which I made to the Lord:

8 For while I was living in Geshur in Aram, your servant made an oath, saying, If ever the Lord lets me come back to Jerusalem, I will give him worship in Hebron.

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

10 But Absalom at the same time sent watchers through all the tribes of Israel to say, At the sound of the horn you are to say, Absalom is king in Hebron.

11 And with Absalom, at his request, went two hundred men from Jerusalem, who were completely unconscious of his designs.

12 And Absalom sent for Ahithophel the Gilonite, one of David's helpers, from Giloh his town, while he was making the offerings. And the design against David became strong, for more and more people were joined to Absalom.

13 And one came to David and said, The hearts of the men of Israel have gone after Absalom.
