2 Samuel 20:8-10
New International Version
8 While they were at the great rock in Gibeon,(A) Amasa came to meet them. Joab(B) was wearing his military tunic, and strapped over it at his waist was a belt with a dagger in its sheath. As he stepped forward, it dropped out of its sheath.
9 Joab said to Amasa, “How are you, my brother?” Then Joab took Amasa by the beard with his right hand to kiss him. 10 Amasa was not on his guard against the dagger(C) in Joab’s(D) 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 Bikri.
