7 After four years, Absalom said to the king, "Let me go to Hebron to offer a sacrifice to the Lord and fulfill a vow I made to him. 8 For while your servant was at Geshur in Aram, I promised to sacrifice to the Lord in Hebron if he would bring me back to Jerusalem." 9 "All right," the king told him. "Go and fulfill your vow." So Absalom went to Hebron. 10 But while he was there, he sent secret messengers to all the tribes of Israel to stir up a rebellion against the king. "As soon as you hear the ram's horn," his message read, "you are to say, 'Absalom has been crowned king in Hebron.'" 11 He took 200 men from Jerusalem with him as guests, but they knew nothing of his intentions. 12 While Absalom was offering the sacrifices, he sent for Ahithophel, one of David's counselors who lived in Giloh. Soon many others also joined Absalom, and the conspiracy gained momentum.

Commentary on 2 Samuel 15:7-12

(Read 2 Samuel 15:7-12)

See how willing tender parents are to believe the best concerning their children. But how easy and how wicked is it, for children to take advantage of good parents, and to deceive them with the show of religion! The principal men of Jerusalem joined Absalom's feast upon his sacrifice. Pious persons are glad to see others appear religious, and this gives occasion for deceptions. The policy of wicked men, and the subtlety of Satan, are exerted to draw good persons to countenance base designs.
