7 And it came to pass after forty years, that Absalom said unto the king, I pray you, let me go and pay my vow, which I have vowed unto the LORD, in Hebron.
8 For your servant vowed a vow while I abode at Geshur in Aram, saying, If the LORD shall bring me again indeed to Jerusalem, then I will serve the LORD.
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 you hear the sound of the trumpet, then you shall say, Absalom reigns in Hebron.
11 And with Absalom went two hundred men out of Jerusalem, that were called; and they went along innocently, and they knew not any thing.
12 And Absalom sent for Ahithophel the Gilonite, David's counselor, from his city, even from Giloh, while he offered 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 have gone after Absalom.
