The long-awaited reconciliation between a father and his estranged son finally takes place after a steady campaign of pressure. Joab approaches the king to deliver the message. He takes this step not out of any great desire, but from a practical realization that Absalom will stop at nothing to get his way. Furthermore, for Joab, the issue is not a matter of deep principle [ביאור שטיינזלץ]. Joab successfully paves the way, and the king summons Absalom, who arrives at his command and bows down in total submission [אברבנאל].
Outwardly, the fractured relationship appears fully repaired. David treats Absalom with obvious compassion and warmth, acting like a father who lovingly spares a devoted son [אברבנאל, ביאור שטיינזלץ]. Yet, a closer look at the interaction reveals a deep reservation in David's attitude. When the king kisses his son, it is not an intimate kiss on the mouth, but rather a measured kiss placed on the hand, shoulder, or body [רלב״ג, מלבי״ם]. This specific gesture is meant to deliver a hidden message. David is signaling that while he agrees to peace, he has no intention of naming Absalom as his royal successor, despite his status as a firstborn son [מלבי״ם].
