2 Samuel 20:8-10

Revised Standard Version Catholic Edition

⁸ When they were at the great stone which is in Gibeon, Ama′sa came to meet them. Now Jo′ab was wearing a soldier’s garment, and over it was a girdle with a sword in its sheath fastened upon his loins, and as he went forward it fell out. ⁹ And Jo′ab said to Ama′sa, “Is it well with you, my brother?” And Jo′ab took Ama′sa by the beard with his right hand to kiss him. ¹⁰ But Ama′sa did not observe the sword which was in Jo′ab’s hand; so Jo′ab struck him with it in the body, and shed his bowels to the ground, without striking a second blow; and he died.^[a]

Then Jo′ab and Abi′shai his brother pursued Sheba the son of Bichri.
