שמואל ב, פרק ג׳, פסוק כ׳

The meeting between Abner and David is defined by mutual gestures of respect, laying a solid foundation for their new agreement. When Abner arrives in Hebron, he is accompanied by twenty men, giving his visit a dignified and official character [ביאור שטיינזלץ]. In response to this formal arrival, David welcomes Abner with great honor and hosts a feast for him and his men [ביאור שטיינזלץ, אברבנאל]. Such a banquet represents a true celebratory meal, traditionally named for the drinking of wine that accompanies it [מצודת ציון].

This respectful reception successfully paved the way for the next phase of their plan. Following the feast, Abner received permission to depart and gather all of Israel to officially crown David as king. This critical agreement was secured just moments before Joab and David's servants returned with great spoils from a raid in Philistine territory [אברבנאל].
