Charles Ellicott Commentary 2 Samuel 14:32

"And Absalom answered Joab, Behold, I sent unto thee, saying, Come hither, that I may send thee to the king, to say, Wherefore am I come from Geshur? it were better for me to be there still. Now therefore let me see the king`s face; and if there be iniquity in me, let him kill me." — 2 Samuel 14:32 (ASV)

If there be any iniquity. —Absalom makes no acknowledgment of having done wrong, but simply says that this state of half-reconciliation is intolerable. He must either be punished or fully pardoned. Joab’s intercession accomplishes its purpose; the king receives Absalom, and kisses him in token of complete reconciliation. In this David showed great weakness, for which he afterwards suffered severely.
