2 Samuel 20:8-10

New Century Version

⁸ When Joab and the army came to the great rock at Gibeon, Amasa came out to meet them. Joab was wearing his uniform, and at his waist he wore a belt that held his sword in its case. As Joab stepped forward, his sword fell out of its case. ⁹ Joab asked Amasa, “Brother, is everything all right with you?” Then with his right hand he took Amasa by the beard to kiss him. ¹⁰ Amasa was not watching the sword in Joab’s hand. So Joab pushed the sword into Amasa’s stomach, causing Amasa’s insides to spill onto the ground. Joab did not have to stab Amasa again; he was already dead. Then Joab and his brother Abishai continued to chase Sheba son of Bicri.
