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.For thy servant vowed a vow while I abode at Geshur in Syria,.... When at his grandfather's court there:

saying, if the Lord will bring me again indeed to Jerusalem; which he might be sincerely desirous of:

then I will serve the Lord; but it is a question whether he ever made a vow to this purpose, or concerned himself about serving the Lord; but it rather may be, this was a lie of his, now framed in order to get leave of the king to go to Hebron.
