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.

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.
