2nd Samuel 15:12

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 reigneth in Hebron.

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

12 And 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.

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

14 And David said unto all his servants that were with him at Jerusalem, Arise, and let us flee; for we shall not else escape from Absalom: make speed to depart, lest he overtake us suddenly, and bring evil upon us, and smite the city with the edge of the sword.

15 And the king's servants said unto the king, Behold, thy servants are ready to do whatsoever my lord the king shall appoint.
