שמואל ב, פרק כ׳, פסוק ט׳

Joab approaches Amasa with a warm and heartfelt greeting, specifically addressing him as a brother. This title reflects more than just their shared family ties. At this point in time, the two men are officially considered allies, making the friendly approach seem completely natural and expected.

As he delivers this greeting, Joab takes firm hold of Amasa's beard with his right hand. This specific physical gesture is meant to look like an act of deep personal affection. By holding the beard in this manner, Joab creates a convincing pretense of closeness, making it appear as though he is simply leaning in to give him a kiss.
