13:39 Go forth - And could not he recalled, to visit him, or to send for him. What amazing weakness was this! At first he could not find in his heart, to do justice to the ravisher of his sister! And now he can almost find in his heart to receive into favour the murderer of his brother? How can we excuse David from the sin of Eli; who honoured his sons more than God?
13:30-39 Jonadab was as guilty of Ammon's death, as of his sin; such false friends do they prove, who counsel us to do wickedly. Instead of loathing Absalom as a murderer, David, after a time, longed to go forth to him. This was David's infirmity: God saw something in his heart that made a difference, else we should have thought that he, as much as Eli, honoured his sons more than God.
