Joab said to Amasa, "How are you, my brother?" Then Joab took Amasa by the beard with his right hand to kiss him.
Amasa was not on his guard against the dagger1 in Joab's2 hand, and Joab plunged it into his belly, and his intestines spilled out on the ground. Without being stabbed again, Amasa died. Then Joab and his brother Abishai pursued Sheba son of Bicri.
